Psalms 51:2-6

Wash me throughly from mine iniquity, and cleanse me from my sin.

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.
