The Seven-Faceted Blessing (Hebrew: ברכה אחת מעין שבע, berakha aḥat me‘en sheva‘) is a blessing recited in the Jewish liturgy of Friday evenings. It is similar to the out-loud repetition of the `Amida, which is recited in each daytime prayer; on typical evenings, the `Amida is recited only silently, with no out-loud repetition, but on Friday nights, in honor of the Sabbath, the Seven-Faceted Blessing is recited as an abbreviated repetition.
The Seven-Faceted Blessing begins with the beginning of the text of the first blessing of the `Amida; continues with the paragraph “Magen Avot” (מגן אבות), which summarizes the themes of all seven blessings of the Sabbath `Amida; and concludes with a paragraph about the sanctity of the sabbath, and a concluding sentence: "Blessed art Thou, O Lord, who sanctifies the Sabbath."
The Seven-Faceted Blessing is recited every Friday evening of the year, even if it coincides with a festival or Yom Kippur. This is in contrast to most of the Sabbath liturgy, which is jettisoned if a particular Sabbath falls on a festival or on Yom Kippur.
The text of the Seven-Faceted Blessing (in accordance with the Ashkenazic version—other traditions have very similar versions—can be found in Seder `Avodat Yisra’el on pp. 190–191. The text used in most Western Sephardic Communities can be found in "Seder Tefilah" of Mantua.
In medieval Europe, it was fairly common for congregations to insert special poems, called Magen Avot piyyutim, into the middle of this blessing; however, this is no longer common today.
