Psalms 51:1-3

To the chief Musician, A Psalm of David, when Nathan the prophet came unto him, after he had gone in to Bath-sheba. Have mercy upon me, O God, according to thy lovingkindness: according unto the multitude of thy tender mercies blot out my transgressions.

Wash me throughly from mine iniquity, and cleanse me from my sin.

For I acknowledge my transgressions: and my sin is ever before me.
