Chapter 22

This chapter is a psalm, a psalm of praise; we find it afterwards inserted among David’s psalms (Ps. 18:1-50) with some little variation. We have it here as it was first composed for his own closed and his own harp; but there we have it as it was afterwards delivered to the chief musician for the service of the church, a second edition with some amendments; for, though it was calculated primarily for David’s case, yet it might indifferently serve the devotion of others, in giving thanks for their deliverances; or it was intended that his people should thus join with him in his thanksgivings, because, being a public person, his deliverances were to be accounted public blessings and called for public acknowledgments. The inspired historian, having largely related David’s deliverances in this and the foregoing book, and one particularly in the close of the foregoing chapter, thought fit to record this sacred poem as a memorial of all that had been before related. Some think that David penned this psalm when he was old, upon a general review of the mercies of his life and the many wonderful preservations God had blessed him with, from first to last. We should in our praises, look as far back as we can, and not suffer time to wear out the sense of God’s favours. Others think that he penned it when he was young, upon occasion of some of his first deliverances, and kept it by him for his use afterwards, and that, upon every new deliverance, his practice was to sing this song. But the book of Psalms shows that he varied as there was occasion, and confined not himself to one form. Here is, I. The title of the psalm, 2 Sam. 22:1. II. The psalm itself, in which, with a very warm devotion and very great fluency and copiousness of expression, 1. He gives glory to God. 2. He takes comfort in him; and he finds matter for both, (1.) In the experiences he had of God’s former favours. (2.) In the expectations he had of his further favours. These are intermixed throughout the whole psalm.
