For the choirmaster. Of David the servant of the LORD, who sang this song to the LORD on the day the LORD had delivered him from the hand of all his enemies and from the hand of Saul. He said:
For innumerable evils have compassed me about: mine iniquities have taken hold upon me, so that I am not able to look up; they are more than the hairs of mine head: therefore my heart faileth me.
