Book Two (Psalms 42-72) "Concerning Israel as a Nation"
A Psalm of David, when Nathan the prophet came unto him, after he had gone in to Bathsheba.
1: Have mercy upon me, O God, according to thy lovingkindness: according unto the multitude of thy tender mercies blot out my transgressions.
2: Wash me throughly from mine iniquity, and cleanse me from my sin.
3: For I acknowledge my transgressions: and my sin is ever before me.
4: 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.
5: Behold, I was shapen in iniquity; and in sin did my mother conceive me.
6: Behold, thou desirest truth in the inward parts: and in the hidden part thou shalt make me to know wisdom.
7: Purge me with hyssop, and I shall be clean: wash me, and I shall be whiter than snow.
8: Make me to hear joy and gladness; that the bones which thou hast broken may rejoice.
9: Hide thy face from my sins, and blot out all mine iniquities.
10: Create in me a 
clean heart, O God; and renew a right spirit within me.
11: Cast me not away from thy presence; and take not thy holy spirit from me.
12: Restore unto me the joy of thy salvation; and uphold me with thy free spirit.
13: Then will I teach transgressors thy ways; and sinners shall be converted unto thee.
14: Deliver me from bloodguiltiness, O God, thou God of my salvation: and my tongue shall sing aloud of thy righteousness.
15: O Lord, open thou my lips; and my mouth shall shew forth thy praise.
16: For thou desirest not sacrifice; else would I give it: thou delightest not in burnt offering.
17: The sacrifices of God are a broken spirit: a broken and a contrite heart, O God, thou wilt not despise.
18: Do good in thy good pleasure unto Zion: build thou the walls of Jerusalem.
19: Then shalt thou be pleased with the sacrifices of righteousness, with burnt offering and whole burnt offering: then shall they offer bullocks upon thine altar.
