ourth
penitential psalm.

50:1. Unto the end, a psalm of David,

50:2. When Nathan the prophet came to him, after he had sinned with
Bethsabee. [2 Kings 12.]

50:3. Have mercy on me, O God, according to thy great mercy. And
according to the multitude of thy tender mercies blot out my iniquity.

50:4. Wash me yet more from my iniquity, and cleanse me from my sin.

50:5. For I know my iniquity, and my sin is always before me.

50:6. To thee only have I sinned, and have done evil befoer thee: that
thou mayst be justified in thy words, and mayst overcome when thou art
judged.

50:7. For behold I was conceived in iniquities; and in sins did my
mother conceive me.

50:8. For behold thou hast loved truth: the uncertain and hidden things
of thy wisdom thou hast made manifest to me.

50:9. Thou shalt sprinkle me with hyssop, and I shall be cleansed: thou
shalt wash me, and I shall be made whiter than snow.

50:10. To my hearing thou shalt give joy and gladness: and the bones
that have been humbled shall rejoice.

50:11. Tukrn away thy face from my sins, and blot out all my iniquities.

50:12. Create a clean heart in me, O God: and renew a right spirit
within my bowels.

50:13. Cast me not away from thy face; and take not thy holy spirit from
me.

50:14. Restore unto me the joy of thy salvation, and strengthen me with
a perfect spirit.

50:15. I will teach the unjust thy ways: and the wicked shall be
converted to thee.

50:16. Deliver me from blood, O God, thou God of my salvation: and my
tongue shall extol thy justice.

50:17. O Lord, thou wilt open my lips: and my mouth shall declare thy
praise.

50:18. For if thou hadst desired sacrifice, I would indeed have given
it: with burnt offerings thou wilt not be delighted.

50:19. A sacrifice to God is an afflicted spirit: a contrite and humbled
heart, O God, thou wilt not despise.

50:20. Deal favourably, O Lord, in thy good will with Sion; that the
walls of Jerusalem may be built up.

50:21. Then shalt thou accept the sacrifice of justice, oblations and
whole burnt offerings: then shall they lay calves upon thy altar.

Psalms Chapter 51

Quid gloriaris.

David condemneth the wickedness of Doeg, and foretelleth his
destruction.

51:1. Unto the end, understanding for David,

51:2. When Doeg the Edomite came and told Saul: David went to the house
of Achimelech.

51:3. Why dost thou glory in malice, thou that art mighty in iniquity?

51:4. All th
