1 For the Chief Musician. A Psalm of David; when Nathan the prophet came to him, after he had gone in to Bathsheba. Have mercy on me, O God, according to your loving-kindness: According to the multitude of your tender mercies blot out my transgressions.2 Wash me thoroughly from my iniquity, And cleanse me from my sin.3 For I know my transgressions; And my sin is ever before me.
