Psalms 51: 3 - 4, 12 - 13, 18 - 19
3 For I know my transgressions, and my sin is ever before me.
4 Against thee, thee only, have I sinned, and done that which is evil in thy sight, so that thou art justified in thy sentence and blameless in thy judgment.
12 Restore to me the joy of thy salvation, and uphold me with a willing spirit.
13 Then I will teach transgressors thy ways, and sinners will return to thee.
18 Do good to Zion in thy good pleasure; rebuild the walls of Jerusalem,
19 then wilt thou delight in right sacrifices, in burnt offerings and whole burnt offerings; then bulls will be offered on thy altar.
