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.
