Yitro (parsha)

Readings

In traditional Sabbath Torah reading, the parashah is divided into seven readings, or עליות‎, aliyot.

First reading — Exodus 18:1–12

In the first reading (עליה‎, aliyah), Moses' father-in-law Jethro heard all that God had done for the Israelites and brought Moses' wife Zipporah and her two sons Gershom ("I have been a stranger here") and Eliezer ("God was my help") to Moses in the wilderness at Mount Sinai. Jethro rejoiced, blessed God, and offered sacrifices to God.

Second reading — Exodus 18:13–23

In the second reading (עליה‎, aliyah), the people stood from morning until evening waiting for Moses to adjudicate their disputes. Jethro counseled Moses to make known the law, and then choose capable, trustworthy, God-fearing men to serve as chiefs to judge the people, bringing only the most difficult matters to Moses.

Third reading — Exodus 18:24–27

In the short third reading (עליה‎, aliyah), Moses heeded Jethro's advice. Then Moses bade Jethro farewell, and Jethro went home.

Fourth reading — Exodus 19:1–6

In the fourth reading (עליה‎, aliyah), three months to the day after the Israelites left Egypt, they entered the wilderness at the foot of Mount Sinai. Moses went up Mount Sinai, and God told him to tell the Israelites that if they would obey God faithfully and keep God's covenant, they would be God's treasured possession, a kingdom of priests, and a holy nation.

Fifth reading — Exodus 19:7–19

In the fifth reading (עליה‎, aliyah), when Moses told the elders, all the people answered: "All that the Lord has spoken we will do!" and Moses brought the people's words back to God. God instructed Moses to have the people stay pure, wash their clothes, and prepare for the third day, when God would come down in the sight of the people, on Mount Sinai. God told Moses to set bounds around the mountain, threatening whoever touched the mountain with death, and Moses did so.

At dawn of the third day, there was thunder, lightning, a dense cloud upon the mountain, and a very loud blast of the horn. Moses led the people to the foot of the mountain. Mount Sinai was all in smoke, the mountain trembled violently, the blare of the horn grew louder and louder, and God answered Moses in thunder.

Sixth reading — Exodus 19:20–20:14

In the sixth reading (עליה‎, aliyah), God came down on the top of Mount Sinai, and called Moses up. God again commanded Moses to warn the people not to break through.

God spoke the Ten Commandments:

1. "I the Lord am your God."
2. "You shall have no other gods besides Me. You shall not make for yourself a sculptured image, or any likeness of what is in the heavens above, or on the earth below, or in the waters under the earth. You shall not bow down to them or serve them."
3. "You shall not swear falsely by the name of the Lord your God."
4. "Remember the Sabbath day and keep it holy."
5. "Honor your father and your mother."
6. "You shall not murder."
7. "You shall not commit adultery."
8. "You shall not steal."
9. "You shall not bear false witness."
10. "You shall not covet . . . anything that is your neighbor's."

Seventh reading — Exodus 20:15–23

In the seventh reading (עליה‎, aliyah), seeing the thunder, lightning, and the mountain smoking, the people fell back and asked Moses to speak to them instead of God. God told Moses to tell the people not make any gods of silver or gold, but an altar of earth for sacrifices. God prohibited hewing the stones to make a stone altar. And God prohibited ascending the altar by steps, so as not to exposed the priests' nakedness.

Readings according to the triennial cycle

Jews who read the Torah according to the triennial cycle of Torah reading may read the parashah according to a different schedule. Some congregations that read the Torah according to the triennial cycle read the parashah in three divisions with the Ten Commandments in years two and three, while other congregations that read the Torah according to the triennial cycle nonetheless read the entire parashah with Ten Commandments every year.

In ancient parallels

The parashah has parallels in these ancient sources:

Exodus chapter 20

The early Third Millenium BCE Sumerian wisdom text Instructions of Shuruppak contains maxims that parallel the Ten Commandments, including:

Don’t steal anything; don’t kill yourself! . . . My son, don’t commit murder . . . Don’t laugh with a girl if she is married; the slander (arising from it) is strong! . . . Don’t plan lies; it is discrediting . . . Don’t speak fraudulently; in the end it will bind you like a trap.

In inner-biblical interpretation

The parashah has parallels or is discussed in these Biblical sources:

Exodus chapter 20

Exodus 34:28 and Deuteronomy 4:13 and 10:4 refer to the Ten Commandments as the “ten words” (עֲשֶׂרֶת הַדְּבָרִים‎, aseret ha-devarim).

In classical rabbinic interpretation

The parashah is discussed in these rabbinic sources from the era of the Mishnah and the Talmud:

Exodus chapter 18

The Tannaim debated what news Jethro heard in Exodus 18:1 that caused him to adopt the faith of Moses. Rabbi Joshua said that Jethro heard of the Israelites' victory over the Amalekites, as Exodus 17:13 reports the results of that battle immediately before Exodus 18:1 reports Jethro's hearing of the news. Rabbi Eleazar of Modim said that Jethro heard of the giving of the Torah, for when God gave Israel the Torah, the sound travelled from one end of the earth to the other, and all the world's kings trembled in their palaces and sang, as Psalm 29:9 reports, "The voice of the Lord makes the hinds to tremble . . . and in His temple all say: 'Glory.'" The kings then converged upon Balaam and asked him what the tumultuous noise was that they had heard — perhaps another flood, or perhaps a flood of fire. Balaam told them that God had a precious treasure in store, which God had hidden for 974 generations before the creation of the world, and God desired to give it to God's children, as Psalm 29:11 says, "The Lord will give strength to His people." Immediately they all exclaimed the balance of Psalm 29:11: "The Lord will bless His people with peace." Rabbi Eleazar said that Jethro heard about the dividing of the Reed Sea, as Joshua 5:1 reports, "And it came to pass, when all the kings of the Amorites heard how the Lord had dried up the waters of the Jordan before the children of Israel," and Rahab the harlot too told Joshua's spies in Joshua 2:10: "For we have heard how the Lord dried up the water of the Red Sea."

Rabbi Joshua interpreted Exodus 18:6 to teach that Jethro sent a messenger to Moses. Noting that Exodus 18:6 mentions each of Jethro, Zipporah, and Moses' children, Rabbi Eliezer taught that Jethro sent Moses a letter asking Moses to come out to meet Jethro for Jethro's sake; and should Moses be unwilling to do so for Jethro's sake, then to do so for the Zipporah's sake; and should Moses be reluctant to do so for her sake, then to do so the sake of Moses' children.

Rabbi Pappias read the words "And Jethro said: 'Blessed be the Lord'" in Exodus 18:10 as a reproach to the Israelites, for not one of the 600,000 Israelites rose to bless God until Jethro did.

A Midrash expounded on the role of Moses as a judge in Exodus 18:13. Interpreting God’s command in Exodus 28:1, the Sages told that when Moses came down from Mount Sinai, he saw Aaron beating the Golden Calf into shape with a hammer. Aaron really intended to delay the people until Moses came down, but Moses thought that Aaron was participating in the sin and was incensed with him. So God told Moses that God knew that Aaron's intentions were good. The Midrash compared it to a prince who became mentally unstable and started digging to undermine his father's house. His tutor told him not to weary himself but to let him dig. When the king saw it, he said that he knew the tutor’s intentions were good, and declared that the tutor would rule over the palace. Similarly, when the Israelites told Aaron in Exodus 32:1, “Make us a god,” Aaron replied in Exodus 32:1, “Break off the golden rings that are in the ears of your wives, of your sons, and of your daughters, and bring them to me.” And Aaron told them that since he was a priest, they should let him make it and sacrifice to it, all with the intention of delaying them until Moses could come down. So God told Aaron that God knew Aaron’s intention, and that only Aaron would have sovereignty over the sacrifices that the Israelites would bring. Hence in Exodus 28:1, God told Moses, “And bring near Aaron your brother, and his sons with him, from among the children of Israel, that they may minister to Me in the priest's office.” The Midrash told that God told this to Moses several months later in the Tabernacle itself when Moses was about to consecrate Aaron to his office. Rabbi Levi compared it to the friend of a king who was a member of the imperial cabinet and a judge. When the king was about to appoint a palace governor, he told his friend that he intended to appoint the friend’s brother. So God made Moses superintendent of the palace, as Numbers 7:7 reports, “My servant Moses is . . . is trusted in all My house,” and God made Moses a judge, as Exodus 18:13 reports, “Moses sat to judge the people.” And when God was about to appoint a High Priest, God notified Moses that it would be his brother Aaron.

Rabbi Berekiah taught in the name of Rabbi Hanina that judges must possess seven qualities, and Exodus 18:21 enumerates four: "Moreover you shall provide out of all the people able men, such as fear God, men of truth, hating unjust gain." And Deuteronomy 1:13 mentions the other three: They must be "wise men, and understanding, and full of knowledge." Scripture does not state all seven qualities together to teach that if people possessing all the seven qualities are not available, then those possessing four are selected; if people possessing four qualities are not available, then those possessing three are selected; and if even these are not available, then those possessing one quality are selected, for as Proverbs 31:10 says, "A woman of valor who can find?"

Exodus chapter 19

The Mekhilta of Rabbi Ishmael deduced from the use of the singular form of the verb "encamped" (vayichan, וַיִּחַן‎) in Exodus 19:2 that all the Israelites agreed and were of one mind.

A Midrash taught that God created the world so that the upper realms should be for the upper beings, and the lower realms for the lower, as Psalm 115:16 says, “The heavens are the heavens of the Lord, but the earth has He given to the children of men.” Then Moses changed the earthly into heavenly and the heavenly into earthly, for as Exodus 19:3 reports, “Moses went up to God,” and then Exodus 19:20 reports, “The Lord came down upon Mount Sinai.”

Rabbi Eliezer interpreted the words, "And how I bore you on eagles' wings," in Exodus 19:4 to teach that God rapidly gathered all the Israelites and brought them to Rameses. And the Mekhilta of Rabbi Ishmael further deduced from Exodus 19:4 that the Israelites traveled from Rameses to Succoth in the twinkling of an eye.

Reading the words, "And how I bore you on eagles' wings," in Exodus 19:4, the Mekhilta of Rabbi Ishmael taught that eagles differ from all other birds because other birds carry their young between their feet, being afraid of other birds flying higher above them. Eagles, however, fear only people who might shoot arrows at them from below. Eagles, therefore, prefer that the arrows hit them rather than their children. The Mekhilta of Rabbi Ishmael compared this to a man who walked on the road with his son in front of him. If robbers, who might seek to capture his son, come from in front, the man puts his son behind him. If a wolf comes from behind, the man puts his son in front of him. If robbers come from in front and wolves from behind, the man puts his son on his shoulders. As Deuteronomy 1:31 says, "You have seen how the Lord your God bore you, as a man bears his son."

Reading Exodus 19:4, a Midrash taught that God did not conduct God's Self with the Israelites in the usual manner. For usually when one acquired servants, it was on the understanding that the servants drew the master's carriage. God, however, did not do so, for God bore the Israelites, for in Exodus 19:4, God says to the Israelites, "I bore you on eagles' wings."

A Midrash likened God to a bridegroom and Israel to a bride, and taught that Exodus 19:10 reports that God betrothed Israel at Sinai. The Midrash noted that the Rabbis taught that documents of betrothal and marriage are written only with the consent of both parties, and the bridegroom pays the scribe’s fee. The Midrash then taught that God betrothed Israel at Sinai, reading Exodus 19:10 to say, “And the Lord said to Moses: ‘Go to the people and betroth them today and tomorrow.’” The Midrash taught that in Deuteronomy 10:1, God commissioned Moses to write the document, when God directed Moses, “Carve two tables of stone.” And Deuteronomy 31:9 reports that Moses wrote the document, saying, “And Moses wrote this law.” The Midrash then taught that God compensated Moses for writing the document by giving him a lustrous countenance, as Exodus 34:29 reports, “Moses did not know that the skin of his face sent forth beams.”

The Mishnah noted that oxen were the same as all other beasts insofar as they were required by Exodus 19:12–13 to keep away from Mount Sinai.

The Gemara cited Exodus 19:15 to explain how Moses decided to abstain from marital relations so as to remain pure for his communication with God. A Baraita taught that Moses did three things of his own understanding, and God approved: (1) Moses added one day of abstinence of his own understanding; (2) he separated himself from his wife (entirely, after the Revelation); and (3) he broke the Tablets of Stone (on which God had written the Ten Commandments). The Gemara explained that to reach his decision to separate himself from his wife, Moses applied an a fortiori (kal va-chomer) argument to himself. Moses noted that even though the Shechinah spoke with the Israelites on only one definite, appointed time (at Mount Sinai), God nonetheless instructed in Exodus 19:15, "Be ready against the third day: come not near a woman." Moses reasoned that if he heard from the Shechinah at all times and not only at one appointed time, how much more so should he abstain from marital contact. And the Gemara taught that we know that God approved, because in Deuteronomy 5:26 (5:27 in the NJPS), God instructed Moses (after the Revelation at Sinai), "Go say to them, 'Return to your tents'" (thus giving the Israelites permission to resume marital relations) and immediately thereafter in Deuteronomy 5:27 (5:28 in the NJPS), God told Moses, "But as for you, stand here by me" (excluding him from the permission to return). And the Gemara taught that some cite as proof of God's approval God's statement in Numbers 12:8, "with him [Moses] will I speak mouth to mouth" (as God thus distinguished the level of communication God had with Moses, after Miriam and Aaron had raised the marriage of Moses and then questioned the distinctiveness of the prophecy of Moses).

The Mishnah deduced from Exodus 19:15 that a woman who emits semen on the third day after intercourse is unclean.

The Rabbis compared the Israelites' encounter at Sinai to Jacob's dream in Genesis 28:12–13. The "ladder" in Jacob's dream symbolizes Mount Sinai. That the ladder is "set upon (מֻצָּב‎, mutzav) the earth" recalls Exodus 19:17, which says, "And they stood (וַיִּתְיַצְּבוּ‎, vayityatzvu) at the nether part of the mount." The words of Genesis 28:12, "and the top of it reached to heaven," echo those of Deuteronomy 4:11, "And the mountain burned with fire to the heart of heaven." "And behold the angels of God" alludes to Moses and Aaron. "Ascending" parallels Exodus 19:3: "And Moses went up to God." "And descending" parallels Exodus 19:14: "And Moses went down from the mount." And the words "and, behold, the Lord stood beside him" in Genesis 28:13 parallel the words of Exodus 19:20: "And the Lord came down upon Mount Sinai."

Rabbi Levi addressed the question that Deuteronomy 4:33 raises: "Did ever a people hear the voice of God speaking out of the midst of the fire, as you have heard, and live?" (Deuteronomy 4:33, in turn, refers back to the encounter at Sinai reported at Exodus 19:18–19, 20:1, and after.) Rabbi Levi taught that the world would not have been able to survive hearing the voice of God in God's power, but instead, as Psalm 29:4 says, "The voice of the Lord is with power." That is, the voice of God came according to the power of each individual — young, old, or infant — to receive it.

Reading the words "And the Lord came down upon mount Sinai, to the top of the mount" in Exodus 19:20, the Mekhilta of Rabbi Ishmael supposed that one might think that God actually descended from heaven and transferred God's Presence to the mountain. Thus the Mekhilta of Rabbi Ishmael noted that Exodus 20:18 (20:19 in the NJPS) says: "You yourselves have seen that I have talked with you from heaven," and deduced that God bent down the heavens, lowering them to the top of the mountain, and spread the heavens as a person spreads a mattress on a bed, and spoke from the heavens as a person would speak from the top of a mattress.

Rabbi Joshua ben Levi taught that when Moses ascended on high (as Exodus 19:20 reports), the ministering angels asked God what business one born of woman had among them. God told them that Moses had come to receive the Torah. The angels questioned why God was giving to flesh and blood the secret treasure that God had hidden for 974 generations before God created the world. The angels asked, in the words of Psalm 8:8, "What is man, that You are mindful of him, and the son of man, that You think of him?" God told Moses to answer the angels. Moses asked God what was written in the Torah. In Exodus 20:2, God said, "I am the Lord your God, Who brought you out of the Land of Egypt." So Moses asked the angels whether the angels had gone down to Egypt or were enslaved to Pharaoh. As the angels had not, Moses asked them why then God should give them the Torah. Again, Exodus 20:3 says, "You shall have no other gods," so Moses asked the angels whether they lived among peoples that engage in idol worship. Again, Exodus 20:7 (20:8 in the NJPS) says, "Remember the Sabbath day, to keep it holy," so Moses asked the angels whether they performed work from which they needed to rest. Again, Exodus 20:6 (20:7 in the NJPS) says, "You shall not take the name of the Lord your God in vain," so Moses asked the angels whether there were any business dealings among them in which they might swear oaths. Again, Exodus 20:11 (20:12 in the NJPS) says, "Honor your father and your mother," so Moses asked the angels whether they had fathers and mothers. Again, Exodus 20:12 (20:13 in the NJPS) says, "You shall not murder; you shall not commit adultery; you shall not steal," so Moses asked the angels whether there was jealousy among them and whether the Evil Tempter was among them. Immediately, the angels conceded that God's plan was correct, and each angel felt moved to love Moses and give him gifts. Even the Angel of Death confided his secret to Moses, and that is how Moses knew what to do when, as Numbers 17:11–13 reports, Moses told Aaron what to do to make atonement for the people, to stand between the dead and the living, and to check the plague.

Exodus chapter 20

Rabbi Tarfon taught that God came from Mount Sinai (or others say Mount Seir) and was revealed to the children of Esau, as Deuteronomy 33:2 says, “The Lord came from Sinai, and rose from Seir to them,” and “Seir” means the children of Esau, as Genesis 36:8 says, “And Esau dwelt in Mount Seir.” God asked them whether they would accept the Torah, and they asked what was written in it. God answered that it included (in Exodus 20:12 (20:13 in the NJPS) and Deuteronomy 5:16 (5:17 in the NJPS)), “You shall do no murder.” The children of Esau replied that they were unable to abandon the blessing with which Isaac blessed Esau in Genesis 27:40, “By your sword shall you live.” From there, God turned and was revealed to the children of Ishmael, as Deuteronomy 33:2 says, “He shined forth from Mount Paran,” and “Paran” means the children of Ishmael, as Genesis 21:21 says of Ishmael, “And he dwelt in the wilderness of Paran.” God asked them whether they would accept the Torah, and they asked what was written in it. God answered that it included (in Exodus 20:12 (20:13 in the NJPS) and Deuteronomy 5:16 (5:17 in the NJPS)), “You shall not steal.” The children of Ishamel replied that they were unable to abandon their fathers’ custom, as Joseph said in Genesis 40:15 (referring to the Ishamelites’ transaction reported in Genesis 37:28), “For indeed I was stolen away out of the land of the Hebrews.” From there, God sent messengers to all the nations of the world asking them whether they would accept the Torah, and they asked what was written in it. God answered that it included (in Exodus 20:2 (20:3 in the NJPS) and Deuteronomy 5:6 (5:7 in the NJPS)), “You shall have no other gods before me.” They replied that they had no delight in the Torah, therefore let God give it to God’s people, as Psalm 29:11 says, “The Lord will give strength [identified with the Torah] to His people; the Lord will bless His people with peace.” From there, God returned and was revealed to the children of Israel, as Deuteronomy 33:2 says, “And he came from the ten thousands of holy ones,” and the expression “ten thousands” means the children of Israel, as Numbers 10:36 says, “And when it rested, he said, ‘Return, O Lord, to the ten thousands of the thousands of Israel.’” With God were thousands of chariots and 20,000 angels, and God’s right hand held the Torah, as Deuteronomy 33:2 says, “At his right hand was a fiery law to them.”

Rabbi Joshua ben Levi taught that with every single word that God spoke (as Exodus 20:1 reports), the Israelites' souls departed, as Song of Songs 5:6 says: "My soul went forth when He spoke." But if their souls departed at the first word, how could they receive the second word? God revived them with the dew with which God will resurrect the dead, as Psalm 68:10 says, "You, O God, did send a plentiful rain; You did confirm your inheritance, when it was weary." Rabbi Joshua ben Levi also taught that with every word that God spoke, the Israelites retreated a distance of 12 mils, but the ministering angels led them back, as Psalm 68:13 says, "The hosts of angels march, they march (יִדֹּדוּן יִדֹּדוּן‎, yiddodun yiddodun)." Instead of yiddodun ("they march"), Rabbi Joshua ben Levi read yedaddun ("they lead").

Rabbi Abbahu said in the name of Rabbi Johanan that when God gave the Torah, no bird twittered, no fowl flew, no ox lowed, none of the Ophanim stirred a wing, the Seraphim did not say (in the words of Isaiah 6:3) “Holy, Holy,” the sea did not roar, the creatures did not speak, the whole world was hushed into breathless silence and the voice went forth in the words of Exodus 20:2 and Deuteronomy 5:6: “I am the Lord your God.”

Rabbi Levi explained that God said the words of Exodus 20:2 and Deuteronomy 5:6, “I am the Lord your God,” to reassure Israel that just because they heard many voices at Sinai, they should not believe that there are many deities in heaven, but rather they should know that God alone is God.

Rabbi Tobiah bar Isaac read the words of Exodus 20:2 and Deuteronomy 5:6, “I am the Lord your God,” to teach that it was on the condition that the Israelites acknowledged God as their God that God (in the continuation of Exodus 20:2 and Deuteronomy 5:6) “brought you out of the land of Egypt.” And a Midrash compared “I am the Lord your God” to a princess who having been taken captive by robbers, was rescued by a king, who subsequently asked her to marry him. Replying to his proposal, she asked what dowry the king would give her, to which the king replied that it was enough that he had rescued her from the robbers. (So God’s delivery of the Israelites from Egypt was enough reason for the Israelites to obey God’s commandments.)

Rabbi Levi said that the section beginning at Leviticus 19:1 was spoken in the presence of the whole Israelite people, because it includes each of the Ten Commandments, noting that: (1) Exodus 20:2 says, "I am the Lord your God," and Leviticus 19:3 says, "I am the Lord your God"; (2) Exodus 20:2–3 says, "You shall have no other gods," and Leviticus 19:4 says, "Nor make to yourselves molten gods"; (3) Exodus 20:6 (20:7 in the NJPS) says, "You shall not take the name of the Lord your God in vain," and Leviticus 19:12 says, "And you shall not swear by My name falsely"; (4) Exodus 20:7 (20:8 in the NJPS) says, "Remember the Sabbath day," and Leviticus 19:3 says, "And you shall keep My Sabbaths"; (5) Exodus 20:11 (20:12 in the NJPS) says, "Honor your father and your mother," and Leviticus 19:3 says, "You shall fear every man his mother, and his father"; (6) Exodus 20:12 (20:13 in the NJPS) says, "You shall not murder," and Leviticus 19:16 says, "Neither shall you stand idly by the blood of your neighbor"; (7) Exodus 20:12 (20:13 in the NJPS) says, "You shall not commit adultery," and Leviticus 20:10 says, "Both the adulterer and the adulteress shall surely be put to death; (8) Exodus 20:12 (20:13 in the NJPS) says, "You shall not steal," and Leviticus 19:11 says, "You shall not steal"; (9) Exodus 20:12 (20:13 in the NJPS) says, "You shall not bear false witness," and Leviticus 19:16 says, "You shall not go up and down as a talebearer"; and (10) Exodus 20:13 (20:14 in the NJPS) says, "You shall not covet . . . anything that is your neighbor's," and Leviticus 19:18 says, "You shall love your neighbor as yourself."

The Mishnah taught that the priests recited the Ten Commandments daily. The Gemara, however, taught that although the Sages wanted to recite the Ten Commandments along with the Shema in precincts outside of the Temple, they soon abolished their recitation, because the Sages did not want to lend credence to the arguments of the heretics (who might argue that Jews honored only the Ten Commandments).

Rabbi Ishmael interpreted Exodus 20:2 (20:2–3 in the NJPS) and Deuteronomy 5:6 (5:6–7 in the NJPS) to be the first of the Ten Commandments. Rabbi Ishmael taught that Scripture speaks in particular of idolatry, for Numbers 15:31 says, “Because he has despised the word of the Lord.” Rabbi Ishmael interpreted this to mean that an idolater despises the first word among the Ten Words or Ten Commandments in Exodus 20:2 (20:2–3 in the NJPS) and Deuteronomy 5:6 (5:6–7 in the NJPS), “I am the Lord your God . . . . You shall have no other gods before Me.”

The Gemara taught that the Israelites heard the words of the first two commandments (in Exodus 20:2–5 (20:3–6 in the NJPS) and Deuteronomy 5:6–9 (5:7–10 in the NJPS)) directly from God. Rabbi Simlai expounded that a total of 613 commandments were communicated to Moses — 365 negative commandments, corresponding to the number of days in the solar year, and 248 positive commandments, corresponding to the number of the parts in the human body. Rav Hamnuna said that one may derive this from Deuteronomy 33:4, "Moses commanded us Torah, an inheritance of the congregation of Jacob." The letters of the word "Torah" (תּוֹרָה‎) have a numerical value of 611 (as ת‎ equals 400, ו‎ equals 6, ר‎ equals 200, and ה‎ equals 5). And the Gemara did not count among the commandments that the Israelites heard from Moses the commandments, "I am the Lord your God," and, "You shall have no other gods before Me," as the Israelites heard those commandments directly from God.

The Sifre taught that to commit idolatry is to deny the entire Torah.

Tractate Avodah Zarah in the Mishnah, Tosefta, Jerusalem Talmud, and Babylonian Talmud interpreted the laws prohibiting idolatry in Exodus 20:2–5 (20:3–6 in the NJPS) and Deuteronomy 5:6–9 (5:7–10 in the NJPS).

The Mishnah taught that those who engaged in idol worship were executed, whether they served it, sacrificed to it, offered it incense, made libations to it, prostrated themselves to it, accepted it as a god, or said to it "You are my god." But those who embraced, kissed, washed, anointed, clothed, or swept or sprinkled the ground before an idol merely transgressed the negative commandment of Exodus 20:4 (20:5 in the NJPS) and were not executed.

The Gemara reconciled apparently discordant verses touching on vicarious responsibility. The Gemara noted that Deuteronomy 24:16 states: "The fathers shall not be put to death for the children, neither shall the children be put to death for the fathers; every man shall be put to death for his own sin," but Exodus 20:4 (20:5 in the NJPS) says: "visiting the iniquity of the fathers upon the children." The Gemara cited a Baraita that interpreted the words "the iniquities of their fathers shall they pine away with them" in Leviticus 26:39 to teach that God punishes children only when they follow their parents' sins. The Gemara then questioned whether the words "they shall stumble one upon another" in Leviticus 26:37 do not teach that one will stumble through the sin of the other, that all are held responsible for one another. The Gemara answered that the vicarious responsibility of which Leviticus 26:37 speaks is limited to those who have the power to restrain their fellow from evil but do not do so.

Tractates Nedarim and Shevuot in the Mishnah, Tosefta, Jerusalem Talmud, and Babylonian Talmud interpreted the laws of vows and oaths in Exodus 20:6 (20:7 in the NJPS), Leviticus 5:1–10 and 19:12, Numbers 30:2–17, and Deuteronomy 23:24.

Tractate Shabbat in the Mishnah, Tosefta, Jerusalem Talmud, and Babylonian Talmud interpreted the laws of the Sabbath in Exodus 16:23 and 29; 20:7–10 (20:8–11 in the NJPS); 23:12; 31:13–17; 35:2–3; Leviticus 19:3; 23:3; Numbers 15:32–36; and Deuteronomy 5:11 (5:12 in the NJPS).

The Mishnah interpreted the prohibition of animals working in Exodus 20:9 (20:10 in the NJPS) to teach that on the Sabbath, animals could wear their tethers, and their caretakers could lead them by their tethers and sprinkle or immerse them with water. The Mishnah taught that a donkey could go out with a saddle cushion tied to it, rams strapped, ewes covered, and goats with their udders tied. Rabbi Jose forbade all these, except covering ewes. Rabbi Judah allowed goats to go out with their udders tied to dry, but not to save their milk. The Mishnah taught that animals could not go out with a pad tied to their tails. A driver could not tie camels together and pull one of them, but a driver could take the leads of several camels in hand and pull them. The Mishnah prohibited donkeys with untied cushions, bells, ladder–shaped yokes, or thongs around their feet; fowls with ribbons or leg straps; rams with wagons; ewes protected by wood chips in their noses; calves with little yokes; and cows with hedgehog skins or straps between their horns. The Mishnah reported that Rabbi Eleazar ben Azariah's cow used to go out with a thong between its horns, but without the consent of the Rabbis.

A Midrash cited the words of Exodus 20:9 (20:10 in the NJPS), “And your stranger who is within your gates,” to show God’s injunction to welcome the stranger. The Midrash compared the admonition in Isaiah 56:3, “Neither let the alien who has joined himself to the Lord speak, saying: ‘The Lord will surely separate me from his people.’” (Isaiah enjoined Israelites to treat the convert the same as a native Israelite.) Similarly, the Midrash quoted Job 31:32, in which Job said, “The stranger did not lodge in the street” (that is, none were denied hospitality), to show that God disqualifies no creature, but receives all; the city gates were open all the time and anyone could enter them. The Midrash equated Job 31:32, “The stranger did not lodge in the street,” with the words of Exodus 20:9 (20:10 in the NJPS), Deuteronomy 5:13 (5:14 in the NJPS), and Deuteronomy 31:12, “And your stranger who is within your gates” (which implies that strangers were integrated into the midst of the community). Thus the Midrash taught that these verses reflect the Divine example of accepting all creatures.

The Mishnah taught that every act that violates the law of the Sabbath also violates the law of a festival, except that one may prepare food on a festival but not on the Sabbath.

The Tanna Devei Eliyahu taught that if you live by the commandment establishing the Sabbath (in Exodus 20:7 (20:8 in the NJPS) and Deuteronomy 5:11 (5:12 in the NJPS)), then (in the words of Isaiah 62:8) “The Lord has sworn by His right hand, and by the arm of His strength: ‘Surely I will no more give your corn to be food for your enemies.” If, however, you transgress the commandment, then it will be as in Numbers 32:10–11, when “the Lord’s anger was kindled in that day, and He swore, saying: ‘Surely none of the men . . . shall see the land.’”

A Midrash asked to which commandment Deuteronomy 11:22 refers when it says, "For if you shall diligently keep all this commandment that I command you, to do it, to love the Lord your God, to walk in all His ways, and to cleave to Him, then will the Lord drive out all these nations from before you, and you shall dispossess nations greater and mightier than yourselves." Rabbi Levi said that "this commandment" refers to the recitation of the Shema (Deuteronomy 6:4–9), but the Rabbis said that it refers to the Sabbath, which is equal to all the precepts of the Torah.

The Mishnah taught that both men and women are obligated to carry out all commandments concerning their fathers. Rav Judah interpreted the Mishnah to mean that both men and women are bound to perform all precepts concerning a father that are incumbent upon a son to perform for his father.

A Midrash noted that almost everywhere, Scripture mentions a father's honor before the mother's honor. (See, for example, Exodus 20:11 (20:12 in NJSP), Deuteronomy 5:15 (5:16 in the NJPS), 27:16.) But Leviticus 19:3 mentions the mother first to teach that one should honor both parents equally.

It was taught in a Baraita that Judah the Prince said that God knows that a son honors his mother more than his father, because the mother wins him over with words. Therefore, (in Exodus 20:11 (20:12 in NJSP)) God put the honor of the father before that of the mother. God knows that a son fears his father more than his mother, because the father teaches him Torah. Therefore, (in Leviticus 19:3) God put the fear of the mother before that of the father.

Our Rabbis taught in a Baraita what it means to "honor" and "revere" one's parents within the meaning of Exodus 20:11 (20:12 in NJSP) (honor), Leviticus 19:3 (revere), and Deuteronomy 5:15 (5:16 in the NJPS) (honor). To "revere" means that the child must neither stand nor sit in the parent's place, nor contradict the parent's words, nor engage in a dispute to which the parent is a party. To "honor" means that the child must give the parent food and drink and clothes, and take the parent in and out.

Noting that Exodus 20:11 (20:12 in NJSP) commands, "Honor your father and your mother," and Proverbs 3:9 directs, "Honor the Lord with your substance," the Rabbis taught in a Baraita that Scripture thus likens the honor due to parents to that due to God. Similarly, as Leviticus 19:3 commands, "You shall fear your father and mother," and Deuteronomy 6:13 commands, "The Lord your God you shall fear and you shall serve," Scripture likens the fear of parents to the fear of God. And as Exodus 21:17 commands, "He that curses his father or his mother shall surely be put to death," and Leviticus 24:15 commands, "Whoever curses his God shall bear his sin," Scripture likens cursing parents to cursing God. But the Baraita conceded that with respect to striking (which Exodus 21:15 addresses with regard to parents), that it is certainly impossible (with respect to God). The Baraita concluded that these comparisons between parents and God are only logical, since the three (God, the mother, and the father) are partners in creation of the child. For the Rabbis taught in a Baraita that there are three partners in the creation of a person — God, the father, and the mother. When one honors one's father and mother, God considers it as if God had dwelt among them and they had honored God. And a Tanna taught before Rav Nachman that when one vexes one's father and mother, God considers it right not to dwell among them, for had God dwelt among them, they would have vexed God.

Chapter 9 of Tractate Sanhedrin in the Mishnah and Babylonian Talmud interpreted the laws of murder in Exodus 20:12 (20:13 in the NJPS) and Deuteronomy 5:16 (5:17 in the NJPS). The Mishnah taught that one who intended to kill an animal but killed a person instead was not liable for murder. One was not liable for murder who intended to kill an unviable fetus and killed a viable child. One was not liable for murder who intended to strike the victim on the loins, where the blow was insufficient to kill, but struck the heart instead, where it was sufficient to kill, and the victim died. One was not liable for murder who intended to strike the victim on the heart, where it was enough to kill, but struck the victim on the loins, where it was not, and yet the victim died.

Interpreting the consequences of murder (prohibited in Exodus 20:12 (20:13 in the NJPS) and Deuteronomy 5:16 (5:17 in the NJPS)), the Mishnah taught that God created the first human (Adam) alone to teach that Scripture imputes guilt to one who destroys a single soul of Israel as though that person had destroyed a complete world, and Scripture ascribes merit to one who preserves a single soul of Israel as though that person had preserved a complete world.

The Tanna Devei Eliyahu taught that if you live by the commandment prohibiting murder (in Exodus 20:12 (20:13 in the NJPS) and Deuteronomy 5:16 (5:17 in the NJPS)), then (in the words of Leviticus 26:6) “the sword shall not go through your land.” If, however, you transgress the commandment, then (in God’s words in Leviticus 26:33) “I will draw out the sword after you.”

Rabbi Josiah taught that we learn the formal prohibition against kidnapping from the words "You shall not steal" in Exodus 20:12 (20:13 in the NJPS) (since Deuteronomy 22:7 and Exodus 21:16 merely state the punishment for abduction). Rabbi Johanan taught that we learn it from Leviticus 25:42, "They shall not be sold as bondsmen." The Gemara harmonized the two positions by concluding that Rabbi Josiah referred to the prohibition for abduction, while Rabbi Johanan referred to the prohibition for selling a kidnapped person. Similarly, the Rabbis taught in a Baraita that Exodus 20:12 (20:13 in the NJPS), "You shall not steal," refers to the stealing of human beings. To the potential objection that Exodus 20:12 (20:13 in the NJPS) refers to property theft, the Baraita responded that one of the thirteen principles by which we interpret the Torah is that a law is interpreted by its general context, and the Ten Commandments speak of capital crimes (like murder and adultery). (Thus "You shall not steal" must refer to a capital crime and thus to kidnapping.) Another Baraita taught that the words "You shall not steal" in Leviticus 19:11 refer to theft of property. To the potential objection that Leviticus 19:11 refers to the theft of human beings, the Baraita responded that the general context of Leviticus 19:10–15 speaks of money matters; therefore Leviticus 19:11 must refer to monetary theft.

According to the Mishnah, if witnesses testified that a person was liable to receive 40 lashes, and the witnesses turned out to have perjured themselves, then Rabbi Meir taught that the perjurers received 80 lashes — 40 on account of the commandment of Exodus 20:12 (20:13 in the NJPS) not to bear false witness and 40 on account of the instruction of Deuteronomy 19:19 to do to perjurers as they intended to do to their victims — but the Sages said that they received only 40 lashes.

Rabbi Shimon ben Lakish taught that the commandment of Exodus 20:12 (20:13 in the NJPS) not to bear false witness included every case of false testimony.

Rav Aha of Difti said to Ravina that one can transgress the commandment not to covet in Exodus 20:13 (20:14 in NJSP) and Deuteronomy 5:17 (5:18 in the NJPS) even in connection with something for which one is prepared to pay.

The Mekhilta of Rabbi Ishmael asked whether the commandment not to covet in Exodus 20:13 (20:14 in NJSP) applied so far as to prohibit merely expressing one's desire for one's neighbor's things in words. But the Mekhilta of Rabbi Ishmael noted that Deuteronomy 7:25 says, "You shall not covet the silver or the gold that is on them, nor take it for yourself." And the Mekhilta of Rabbi Ishmael reasoned that just as in Deuteronomy 7:25 the word "covet" applies only to prohibit the carrying out of one's desire into practice, so also Exodus 20:13 (20:14 in NJSP) prohibits only the carrying out of one's desire into practice.

The Mekhilta of Rabbi Simeon distinguished the prohibition of Exodus 20:13 (20:14 in NJSP), "You shall not covet," from that of Deuteronomy 5:17 (5:18 in the NJPS), "neither shall you desire." The Mekhilta of Rabbi Simeon taught that the differing terms mean that one can incur liability for desiring in and of itself and for coveting in and of itself.

Rabbi Ishmael interpreted the words "all the people perceived the thunderings, and the lightnings, and the voice of the horn" in Exodus 20:14 (20:15 in the NJPS) to mean that the people saw what could be seen and heard what could be heard. But Rabbi Akiva said that they saw and heard what was perceivable, and they saw the fiery word of God strike the tablets.

The Gemara taught that Exodus 20:16 (20:17 in the NJPS) sets forth one of the three most distinguishing virtues of the Jewish People. The Gemara taught that David told the Gibeonites that the Israelites are distinguished by three characteristics: They are merciful, bashful, and benevolent. They are merciful, for Deuteronomy 13:18 says that God would "show you (the Israelites) mercy, and have compassion upon you, and multiply you." They are bashful, for Exodus 20:16 (20:17 in the NJPS) says "that God's fear may be before you (the Israelites)." And they are benevolent, for Genesis 18:19 says of Abraham "that he may command his children and his household after him, that they may keep the way of the Lord, to do righteousness and justice." The Gemara taught that David told the Gibeonites that only one who cultivates these three characteristics is fit to join the Jewish People.

A Midrash likened the commandment of Deuteronomy 25:15 to have just weights and measures to that of Exodus 20:19 (20:20 in the NJPS) not to make gods of silver, or gods of gold. Reading Deuteronomy 25:15, Rabbi Levi taught that blessed actions bless those who are responsible for them, and cursed actions curse those who are responsible for them. The Midrash interpreted the words of Deuteronomy 25:15, "A perfect and just weight you shall have," to mean that if one acts justly, one will have something to take and something to give, something to buy and something to sell. Conversely, the Midrash read Deuteronomy 25:13–14 to teach, "You shall not have possessions if there are in your bag diverse weights, a great and a small. You shall not have possessions if there are in your house diverse measures, a great and a small." Thus, if one does employ deceitful measures, one will not have anything to take or give, to buy or sell. The Midrash taught that God tells businesspeople that they "may not make" one measure great and another small, but if they do, they "will not make" a profit. The Midrash likened this commandment to that of Exodus 20:19 (20:20 in the NJPS) "You shall not make with Me gods of silver, or gods of gold, you shall not make," for if a person did make gods of silver and gold, then that person would not be able to afford to have even gods of wood or stone.

The Mishnah deduced from Exodus 20:20 (20:21 in the NJPS) that even when only a single person sits occupied with Torah, the Shechinah is with the student.

Rabbi Isaac taught that God reasoned that if God said in Exodus 20:20 (20:21 in the NJPS), "An altar of earth you shall make to Me [and then] I will come to you and bless you," thus revealing God's Self to bless the one who built an altar in God's name, then how much more should God reveal God's Self to Abraham, who circumcised himself for God's sake. And thus, "the Lord appear to him."

Bar Kappara taught that every dream has its interpretation. Thus Bar Kappara taught that the "ladder" in Jacob's dream of Genesis 28:12 symbolizes the stairway leading up to the altar in the Temple in Jerusalem. "Set upon the earth" implies the altar, as Exodus 20:20 (20:21 in the NJPS) says, "An altar of earth you shall make for Me." "And the top of it reached to heaven" implies the sacrifices, the odor of which ascended to heaven. "The angels of God" symbolize the High Priests. "Ascending and descending on it" describes the priests ascending and descending the stairway of the altar. And the words "and, behold, the Lord stood beside him" in Genesis 28:13 once again invoke the altar, as in Amos 9:1, the prophet reports, "I saw the Lord standing beside the altar."

In medieval Jewish interpretation

The parashah is discussed in these medieval Jewish sources:

Exodus chapter 18

Interpreting Exodus 18:21 together with Deuteronomy 1:13, Maimonides taught that judges must be on the highest level of righteousness. An effort should be made that they be white-haired, of impressive height, of dignified appearance, and people who understand whispered matters and who understand many different languages so that the court will not need to hear testimony from an interpreter. Maimonides taught that one need not demand that a judge for a court of three possess all these qualities, but a judge must, however, possess seven attributes: wisdom, humility, fear of God, loathing for money, love for truth, being beloved by people at large, and a good reputation. Maimonides cited Deuteronomy 1:13, “Men of wisdom and understanding,” for the requirement of wisdom. Deuteronomy 1:13 continues, “Beloved by your tribes,” which Maimonides read to refer to those who are appreciated by people at large. Maimonides taught that what will make them beloved by people is conducting themselves with a favorable eye and a humble spirit, being good company, and speaking and conducting their business with people gently. Maimonides read Exodus 18:21, “men of power,” to refer to people who are mighty in their observance of the commandments, who are very demanding of themselves, and who overcome their evil inclination until they possess no unfavorable qualities, no trace of an unpleasant reputation, even during their early adulthood, they were spoken of highly. Maimonides read Exodus 18:21, “men of power,” also to imply that they should have a courageous heart to save the oppressed from the oppressor, as Exodus 2:17 reports, “And Moses arose and delivered them.” Maimonides taught that just as Moses was humble, so, too, every judge should be humble. Exodus 18:21 continues “God-fearing,” which is clear. Exodus 18:21 mentions “men who hate profit,” which Maimonides took to refer to people who do not become overly concerned even about their own money; they do not pursue the accumulation of money, for anyone who is overly concerned about wealth will ultimately be overcome by want. Exodus 18:21 continues “men of truth,” which Maimonides took to refer to people who pursue justice because of their own inclination; they love truth, hate crime, and flee from all forms of crookedness.

Exodus chapter 20

Interpreting the prohibition of coveting in Exodus 20:13 (20:14 in NJSP) and desiring in Deuteronomy 5:17 (5:18 in the NJPS), Maimonides taught that any person who covets a servant, a maidservant, a house, or utensils that belong to a colleague, or any other article that the person can purchase from the colleague and pressures the colleague with friends and requests until the colleague agrees to sell, violates a negative commandment, even though the person pays much money for it, as Exodus 20:13 (20:14 in NJSP) says, "Do not covet." Maimonides taught that the violation of this commandment was not punished by lashes, because it does not involve a deed. Maimonides taught that a person does not violate Exodus 20:13 (20:14 in NJSP) until the person actually takes the article that the person covets, as reflected by Deuteronomy 7:25: "Do not covet the gold and silver on these statues and take it for yourself." Maimonides read the word for "covet" in both Exodus 20:13 (20:14 in NJSP) and Deuteronomy 7:25 to refer to coveting accompanied by a deed. Maimonides taught that a person who desires a home, a spouse, utensil, or anything else belonging to a colleague that the person can acquire violates a negative commandment when the person thinks in the person's heart how it might be possible to acquire this thing from the colleague. Maimonides read Deuteronomy 5:17 (5:18 in the NJPS), "Do not desire," to refer even to feelings in the heart alone. Thus, a person who desires another person's property violates one negative commandment. A person who purchases an object the person desires after pressuring the owners and repeatedly asking them, violates two negative commandments. For that reason, Maimonides concluded, the Torah prohibits both desiring in Deuteronomy 5:17 (5:18 in the NJPS) and coveting in Exodus 20:13 (20:14 in NJSP). And if the person takes the article by robbery, the person violates three negative commandments.

Isaac Abravanel noted that the order of Exodus 20:13 (20:14 in NJSP), "You shall not covet your neighbor's house; you shall not covet your neighbor's wife," differs from that in Deuteronomy 5:17 (5:18 in the NJPS), "Neither shall you covet thy neighbor's wife; neither shall you desire your neighbor's house." Abravanel deduced that Exodus 20:13 (20:14 in NJSP) mentions the things that might be coveted in the order that a person has need of them, and what it behooves a person to try to acquire in this world. Therefore, the first coveted item mentioned is a person's house, then the person's spouse, then the person's servants, and lastly the person's animals that do not speak. Deuteronomy 5:17 (5:18 in the NJPS), however, mentions them in the order of the gravity of the sin and evil. The most evil coveting is that of another person's spouse, as in David's coveting of Bathsheba. Next in magnitude of evil comes coveting the house in which one's neighbor lives, lest the person evict the neighbor and take the neighbor's home. Next comes the neighbor's field, for although a person does not live there as in the house, it is the source of the neighbor's livelihood and inheritance, as in the affair of Ahab and the vineyard of Naboth the Jezreelite. After the field Deuteronomy 5:17 (5:18 in the NJPS) mentions servants, who Abravanel valued of lesser importance than one's field. Next come the neighbor's animals, who do not have the faculty of speech, and lastly, to include the neighbor's inanimate moveable property, Deuteronomy 5:17 (5:18 in the NJPS) says "and anything that is your neighbor's."

Maimonides taught that God told the Israelites to erect the altar to God’s name in Exodus 20:20 (20:21 in the NJPS) and instituted the practice of sacrifices generally as transitional steps to wean the Israelites off of the worship of the times and move them toward prayer as the primary means of worship. Maimonides noted that in nature, God created animals that develop gradually. For example, when a mammal is born, it is extremely tender, and cannot eat dry food, so God provided breasts that yield milk to feed the young animal, until it can eat dry food. Similarly, Maimonides taught, God instituted many laws as temporary measures, as it would have been impossible for the Israelites suddenly to discontinue everything to which they had become accustomed. So God sent Moses to make the Israelites (in the words of Exodus 19:6) “a kingdom of priests and a holy nation.” But the general custom of worship in those days was sacrificing animals in temples that contained idols. So God did not command the Israelites to give up those manners of service, but allowed them to continue. God transferred to God’s service what had formerly served as a worship of idols, and commanded the Israelites to serve God in the same manner — namely, to build to a Sanctuary (Exodus 25:8), to erect the altar to God’s name (Exodus 20:20 (20:21 in the NJPS), to offer sacrifices to God (Leviticus 1:2), to bow down to God, and to burn incense before God. God forbad doing any of these things to any other being and selected priests for the service in the temple in Exodus 28:41. By this Divine plan, God blotted out the traces of idolatry, and established the great principle of the Existence and Unity of God. But the sacrificial service, Maimonides taught, was not the primary object of God’s commandments about sacrifice; rather, supplications, prayers, and similar kinds of worship are nearer to the primary object. Thus God limited sacrifice to only one temple (see Deuteronomy 12:26) and the priesthood to only the members of a particular family. These restrictions, Maimonides taught, served to limit sacrificial worship, and kept it within such bounds that God did not feel it necessary to abolish sacrificial service altogether. But in the Divine plan, prayer and supplication can be offered everywhere and by every person, as can be the wearing of tzitzit (Numbers 15:38) and tefillin (Exodus 13:9, 16) and similar kinds of service.

In modern interpretation

The parashah is discussed in these modern sources:

Exodus chapter 18

The 20th century Reform Rabbi Gunther Plaut observed that in Deuteronomy 1:13, the people — not Moses, as recorded in Exodus 18:21 and 24–25 — chose the officials who would share the tasks of leadership and dispute resolution. Jeffrey Tigay, Professor Emeritus at the University of Pennsylvania, however, reasoned that although Moses selected the appointees as recorded in Exodus 18:21 and 24–25, he could not have acted without recommendations by the people, for the officers would have numbered in the thousands (according to the Talmud, 78,600), and Moses could not have known that many qualified people, especially as he had not lived among the Israelites before the Exodus. Professor Robert Alter of the University of California, Berkeley, noted several differences between the accounts in Deuteronomy 1 and Exodus 18, all of which he argued reflected the distinctive aims of Deuteronomy. Jethro conceives the scheme in Exodus 18, but is not mentioned in Deuteronomy 1, and instead, the plan is entirely Moses's idea, as Deuteronomy is the book of Moses. In Deuteronomy 1, Moses entrusts the choice of magistrates to the people, whereas in Exodus 18, he implements Jethro's directive by choosing the judges himself. In Exodus 18, the qualities to be sought in the judges are moral probity and piety, whereas Deuteronomy 1 stresses intellectual discernment.

Exodus chapter 19

Noting that Jewish tradition has not preserved a tradition about Mount Sinai’s location, Plaut observed that had the Israelites known the location in later centuries, Jerusalem and its Temple could never have become the center of Jewish life, for Jerusalem and the Temple would have been inferior in holiness to the God’s mountain. Plaut concluded that Sinai thus became in Judaism, either by design or happenstance, a concept rather than a place.

Alter translated Numbers 15:38 to call for “an indigo twist” on the Israelites’ garments. Alter explained that the dye was not derived from a plant, as is indigo, but from a substance secreted by the murex, harvested off the coast of Phoenicia. The extraction and preparation of this dye were labor-intensive and thus quite costly. It was used for royal garments in many places in the Mediterranean region, and in Israel it was also used for priestly garments and for the cloth furnishings of the Tabernacle. Alter argued that the indigo twist betokened the idea that Israel should become (in the words of Exodus 19:6) a “kingdom of priests and a holy nation” and perhaps also that, as the covenanted people, metaphorically God’s firstborn, the nation as a whole had royal status.

Exodus chapter 20

Although Jewish tradition came to consider the words “I am the Lord your God” in Exodus 20:1 the first of the Ten Commandments, many modern scholars saw not a command, but merely a proclamation announcing the Speaker.

In 1980, in the case of Stone v. Graham, the Supreme Court of the United States held unconstitutional a Kentucky statute that required posting the Ten Commandments on the wall of each public classroom in the state. The Court noted that some of the Commandments apply to arguably secular matters, such those at Exodus 20:11–16 (20:12–17 in the NJPS) and Deuteronomy 5:15–20 (5:16–21 in the NJPS), on honoring one’s parents, murder, adultery, stealing, false witness, and covetousness. But the Court also observed that the first part of the Commandments, in Exodus 20:1–10 (20:1–11 in the NJPS) and Deuteronomy 5:6–14 (5:6–15 in the NJPS), concerns the religious duties of believers: worshipping the Lord God alone, avoiding idolatry, not using the Lord’s name in vain, and observing the Sabbath Day. Thus the Court concluded that the pre-eminent purpose for posting the Ten Commandments on schoolroom walls was plainly religious.

Commandments

According to Sefer ha-Chinuch, there are 3 positive and 14 negative commandments in the parashah:

To know there is a God

Not to believe in divinity besides God

Not to make an idol for yourself

Not to worship idols in the manner they are worshiped

Not to worship idols in the four ways we worship God

Not to take God's Name in vain.

To sanctify the Sabbath with Kiddush and Havdalah

Not to do prohibited labor on the Sabbath

To respect your father and mother

Not to murder

Not to commit adultery

Not to kidnap

Not to testify falsely

Not to covet another's possession

Not to make human forms even for decorative purposes

Not to build the altar with hewn stones

Not to climb steps to the altar.

In the liturgy

The second blessing before the Shema speaks of how God "loves His people Israel," reflecting the statement of Exodus 19:5 that Israel is God's people.

The fire surrounding God's Presence in Exodus 19:16–28 is reflected in Psalm 97:3, which is in turn one of the six Psalms recited at the beginning of the Kabbalat Shabbat prayer service.

Reuven Hammer noted that Mishnah Tamid 5:1 recorded what was in effect the first siddur, as a part of which priests daily recited the Ten Commandments.

It is customary for listeners to stand while the reader chants the Ten Commandments in the synagogue, as if the listeners were themselves receiving the revelation at Sinai.

The Lekhah Dodi liturgical poem of the Kabbalat Shabbat service quotes both the commandment of Exodus 20:7 (Exodus 20:8 in the NJPS) to "remember" the Sabbath and the commandment of Deuteronomy 5:11 (Deuteronomy 5:12 in the NJPS) to "keep" or "observe" the Sabbath, saying that they "were uttered as one by our Creator."

And following the Kabbalat Shabbat service and prior to the Friday evening (Ma'ariv) service, Jews traditionally read rabbinic sources on the observance of the Sabbath, including Genesis Rabbah 11:9. Genesis Rabbah 11:9, in turn, interpreted the commandment of Exodus 20:7 (Exodus 20:8 in the NJPS) to "remember" the Sabbath.

The Kiddusha Rabba blessing for the Sabbath day meal quotes Exodus 20:7–10 (Exodus 20:8–11 in the NJPS) immediately before the blessing on wine.

Among the zemirot or songs of praise for the Sabbath day meal, the song Baruch Kel Elyon, written by Rabbi Baruch ben Samuel, quotes Exodus 20:7 (Exodus 20:8 in the NJPS) and in concluding paraphrases Exodus 20:9 (Exodus 20:10 in the NJPS), saying "In all your dwellings, do not do work — your sons and daughters, the servant and the maidservant."

Similarly, among the zemirot for the Sabbath day meal, the song Yom Zeh Mechubad paraphrases Exodus 20:8–10 (Exodus 20:9–11 in the NJPS), saying, "This day is honored from among all days, for on it rested the One Who fashioned the universe. Six days you may do your work, but the Seventh Day belongs to your God. The Sabbath: Do not do on it any work, for everything God completed in six days."

Many Jews study successive chapters of Pirkei Avot (Chapters of the Fathers) on Sabbaths between Passover and Rosh Hashanah. And Avot 3:6 quotes Exodus 20:20 (20:21 in the NJPS) for the proposition that even when only a single person sits occupied with Torah, the Shechinah is with the student.

The Weekly Maqam

In the Weekly Maqam, Sephardi Jews each week base the songs of the services on the content of that week's parashah. For Parashah Yitro, Sephardi Jews apply Maqam Hoseni, the maqam that expresses beauty, which is especially appropriate in this parashah because it is the parashah where the Israelites receive the Ten Commandments.

Haftarah

The haftarah for the parashah is Isaiah 6:1–7:6 and 9:5–6.

Connection to the Parashah

Both the parashah and the haftarah recount God's revelation. Both the parashah and the haftarah describe Divine Beings as winged. Both the parashah and the haftarah report God's presence accompanied by shaking and smoke. And both the parashah and the haftarah speak of making Israel a holy community.
