Psalms 51:1-6

Have mercy upon me, O God, according to thy lovingkindness: According to the multitude of thy tender mercies blot out my transgressions. Wash me thoroughly from mine iniquity, And cleanse me from my sin. For I know my transgressions; And my sin is ever before me. 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.
