Psalms 51: 3 - 6, 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.
5 Behold, I was brought forth in iniquity, and in sin did my mother conceive me.
6 Behold, thou desirest truth in the inward being; therefore teach me wisdom in my secret heart.
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.
