Psalms 51:4-7

Against thee, thee only, have I sinned, And done that which is evil in thy sight; That thou mayest be justified when thou speakest, And be clear when thou judgest. Behold, I was brought forth in iniquity; And in sin did my mother conceive me. Behold, thou desirest truth in the inward parts; And in the hidden part thou wilt make me to know wisdom. Purify me with hyssop, and I shall be clean: Wash me, and I shall be whiter than snow.
