Have mercy upon me, O God, according to Thy great mercy: according to the multitude of Thy tender mercies blot out mine iniquity. Wash me thoroughly from mine iniquity, and cleanse me from my sin. For I acknowledge mine iniquity: and my sin is ever before me. Against Thee only have I sinned, and done evil in Thy sight: that Thou mightest be justified in Thy words, and prevail when Thou art judged. For behold, I was shapened in iniquity: and in sin did my mother conceive me. For behold, Thou hast loved truth: the unclear and hidden things of Thy wisdom Thou hast made clear to me. Thou shalt sprinkle me with hyssop, and I shall be clean: Thou shalt wash me, and I shall be whiter than snow. Thou shalt make me to hear joy and gladness: the bones which Thou hast broken shall rejoice. Turn away Thy face from my sins, and blot out all my iniquities. Create in me a clean heart, O God: and renew a right spirit within me. Cast me not away from Thy presence: and take not Thy Holy Spirit from me. Restore unto me the joy of Thy salvation: and steady me with a guiding Spirit. Then will I teach transgressors Thy ways: and the impious shall be converted unto Thee. Deliver me from blood-guiltiness, O God, Thou God of my salvation: and my tongue shall sing aloud of Thy righteousness. O Lord, open Thou my lips: and my mouth shall declare Thy praise. For if hadst Thou desired sacrifice, I would have given it Thee: Thou delightest not in burnt offerings. Sacrifices to God are a contrite spirit: a contrite and humble heart, O God, Thou wilt not despise. Do good, O Lord, in Thy good will unto Sion: that the walls of Jerusalem may be built up. Then shalt Thou be pleased with the sacrifice of righteousness, with burnt-offering and whole-burnt offerings: then shall they offer bullocks upon Thine altar.
*Psalm 51 in the numbering of the Masoretic text
