Psalm 51:18
This psalm purports to be a psalm of David, and the contents of it accord with this supposition, and with the statement in the title in regard to the occasion on which it was composed. There would be no difficulty on the subject, and no ground for hesitation, in regard to the author and the occasion on which it was composed, if it were not for the prayer in Psalm 51:18, “Do good in thy good pleasure unto Zion; build thou the walls of Jerusalem,” which, it has been maintained by DeWette, Rosenmuller, Venema, and others, must have been written in the time of the Babylonian cxile. Except this, it is admitted on all hands that the psalm in its composition accords entirely with the statement in the title, that it was composed by David. It has, in fact, been generally admitted that the psalm “was” composed by David, though it is the opinion of Rosenmuller, Venema, and Doederlein, that the last two verses were added by a later hand.
