1 Unto the end, a psalm of David, when Nathan the prophet came to him after he had sinned with Bethsabee. Have mercy on me, O God, according to thy great mercy. And according to the multitude of thy tender mercies blot out my iniquity.

2 Wash me yet more from my iniquity, and cleanse me from my sin.

3 For I know my iniquity, and my sin is always before me.

4 To thee only have I sinned, and have done evil before thee: that thou mayst be justified in thy words and mayst overcome when thou art judged.

5 For behold I was conceived in iniquities; and in sins did my mother conceive me.

6 For behold thou hast loved truth: the uncertain and hidden things of thy wisdom thou hast made manifest to me.

7 Thou shalt sprinkle me with hyssop, and I shall be cleansed: thou shalt wash me, and I shall be made whiter than snow.

8 To my hearing thou shalt give joy and gladness: and the bones that have been humbled shall rejoice.

9 Turn away thy face from my sins, and blot out all my iniquities.

10 Create a clean heart in me, O God: and renew a right spirit within my bowels.

11 Cast me not away from thy face; and take not thy holy spirit from me.

12 Restore unto me the joy of thy salvation, and strengthen me with a perfect spirit.

13 I will teach the unjust thy ways: and the wicked shall be converted to thee.

14 Deliver me from blood, O God, thou God of my salvation: and my tongue shall extol thy justice.

15 O Lord, thou wilt open my lips: and my mouth shall declare thy praise.

16 For if thou hadst desired sacrifice, I would indeed have given it: with burnt offerings thou wilt not be delighted.

17 A sacrifice to God is an afflicted spirit: a contrite and humbled heart, O God, thou wilt not despise.

18 Deal favourably, O Lord, in thy good will with Sion; that the walls of Jerusalem may be built up.

19 Then shalt thou accept the sacrifice of justice, oblations and whole burnt offerings: then shall they lay calves upon thy altar.
