Psalm 51:3-7

For I acknowledge my transgressions: And my sin is ever before me. 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. Behold, I was shapen in iniquity; And in sin did my mother conceive me. Behold, thou desirest truth in the inward parts: And in the hidden part thou shalt make me to know wisdom. Purge me with hyssop, and I shall be clean: Wash me, and I shall be whiter than snow.
