Psalm 33 is the 33rd psalm from the Book of Psalms.
In the International Critical Commentary series, Charles and Emilie Briggs described it as follows: "Ps. 33 is a song of praise. (1) A call to worship in the temple with song, music, and shouting (v.1-3), because of the righteousness and kindness of Yahweh (v.4-5). (2) All mankind are called to fear Yahweh, the creator of all things, and disposer of all nations (v.6-10). (3) Yahweh from His heavenly throne inspects all mankind (v.13-15); and victory is not due to armies or warriors (v.16-17). (4) He delivereth those who fear Him (v.18-19); therefore his people long for Him, are glad in him, and trust in His name for victory (v.20-22). A gloss praises the plans of Yahweh as everlastingly secure, and also the happiness of His people (v.11-12)."
Psalm 33 does not contain an ascription to any particular author in the Hebrew text, though the Greek Septuagint ascribes it to David. The Briggses suggest that it dates to the time of the Maccabees.
