Psalm 51:1-4

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. Against thee, thee only, have I sinned, and done this evil in thy sight: That thou mightest be justified when thou speakest, and be clear when thou judgest.
