References in this psalm to "a new song" (v. 3) and to God's frustration of the plans of hostile nations may suggest a time when Israel experienced a remarkable deliverance from foreign enemies, as in the days of Jehoshaphat (2 Chron. 20) or Hezekiah (2 Kings 19). Relevant for any time the people of God reflect on their security in the face of hostile powers, the psalm calls on God's people to rejoice and sing because of God's faithful care (st. 1). As the almighty Creator, God has more than enough power to protect his people (st. 2). Possessing sovereign power over all the world, God can frustrate all plots against his people and effect his own plans for them (st. 3). God's all-seeing eye perceives the devices of worldly powers and watches protectively over his people (st. 4), so they wait in hope for the LORD, rejoicing and trusting in God's unfailing love and protection (st. 5). Marie J. Post (PHH 5) versified this psalm in 1980 for the Psalter Hymnal. See 449 for another (condensed) setting of Psalm 33.
Liturgical Use:
Praise to God as Creator and Ruler of the universe; expressions of trust in God's saving power; reproach of the evil plans of human powers arrayed against the church and the kingdom of God; counsel against reliance on creaturely means; affirmation of the Lord as the believer's only hope for security.
