Psalm 29 is a song of praise. Commentators mention that it is written in the style of some Canaanite poetry and propose that it was written to emphasize that the God of Israel is the real "storm god", not Ba'al.
With its mention of the voice of God shaking the wilderness in verse 8, this psalm has been associated with God's Sinai revelation and with the festival of Shavuot/Pentecost. At Sinai God was said to have been accompanied by his heavenly host, which is encouraged in verse 1 to praise him.
The superscription for this psalm in the Septuagint reads, "A psalm of David commemorating the feast of Exodus, of the temple" (see the Lexham English Septuagint). The "feast of Exodus" here is the Feast of Tabernacles rather than Pentecost, the Feast associated with Israel's wilderness sojourn. At the Temple the recitation of this Psalm accompanied sacrifices on Yom Teruah and at the Feast of Tabernacles (b. Rosh HaShanah 30b; Sukkah 55a).
Esther Menn and David Sandmel give a good explanation of the midrash in an article from a book giving a variety of perspectives on Psalm 29.
This book describes a variety of interpretations and traditions related to the psalm. A chapter on patristic exegesis explains that a number of church fathers saw in verse 3 a reference to the voice that came from heaven when Jesus was baptized as the power of the Holy Spirit descended on him (Mt 3:16-17 and parallels).
Some traditions are associated with the seven times that the "voice of the Lord" sounds in the psalm: For example:
- The seven thunders of Revelation 10:2-4 often have been seen as a reference to them.
- Roman Catholics have related them to the seven sacraments.
- Protestants have associated them with gifts of the Spirit.
