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:
Thou art of purer eyes than to behold evil, and canst not look on iniquity: wherefore lookest thou upon them that deal treacherously, and holdest thy tongue when the wicked devoureth the man that is more righteous than he?
