This psalm is a celebration of God's great goodness to him, and all his people. In it there are some passages which cannot belong to Christ, and some which do not properly belong to David, or to that time and state of the church, but only to Christ, and to the times of the New Testament. He praises God for delivering him out of deep distress, ver. 1-5. Thence takes occasion to speak of the work of our redemption by Christ, ver. 6- 10. Prays for mercy and grace both for himself and for his brethren, ver. 11-17. To the chief musician, A psalm of David.
