2. Samuel 22:29

Sa2 22:29 commences the description of the help which David had already received from God in his conflict with the enemies of Israel, and which he would still receive. 29 For Thou art my lamp, O Jehovah! And Jehovah maketh my darkness bright. 30 For through Thee I run troops, And through my God I leap walls. 31 God - innocent is His way. The word of Jehovah is refined, A shield is He to all who trust in Him. The explanatory כּי, with which the new description of the divine mercy commences, refers to the thought implied in Sa2 22:28, that David belonged to the "afflicted people," whom the Lord always helps. As the Lord delivered him out of the danger of death, because He took pleasure in him, so He also gave him power over all his enemies. For He was his lamp, i.e., He had lifted him out of a condition of depression and contempt into one of glory and honour (see at Sa2 21:17), and would still further enlighten his darkness, i.e., "would cause the light of His salvation to shine upon him and his tribe in all the darkness of their distress" (Hengstenberg). In the psalm the verse reads thus: "For Thou lightest (makest bright) my lamp (or candle), Jehovah my God enlighteneth my darkness;" the bold figure "Jehovah the lamp of David" being more literally explained. The figure is analogous to the one in Psa 27:1, "The Lord is my light;" whilst the form ניר is a later mode of writing נר.

This chapter is a psalm, a psalm of praise; we find it afterwards inserted among David's psalms (Ps. 18) 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 (Sa2 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 i…
