The form of this psalm seems to be dramatical, and several parts of it are spoken in the name of several persons; as it is in the book of the Song of Solomon, and in one part of Ecclesiastes. David speaks in his own name from the beginning to ver. 22, from thence to ver. 25, in the name of the people; and thence to ver. 28, in the name of the priests; and then concludes in his own name. He calls upon all about him to praise God, ver. 1-4. Encourages himself and others to trust in God, from the experience he had had of his power and mercy, ver. 5-18. He gives thanks for his advancement to the throne, as it was a figure of the exaltation of Christ, ver. 19-23. The people, the priests, and the psalmist himself triumph in the prospect of the Redeemer's kingdom, ver. 24-29.
