Psalms 50:3-9

³Have mercy upon me, O God, according to thy great mercy; And according to the multitude of thy compassions blot out my transgression.

⁴Wash me thoroughly from mine iniquity, And cleanse me from my sin.

⁵For I am conscious of mine iniquity; And my sin is continually before me.

⁶Against thee only have I sinned, And done evil before thee: That thou mightest be justified in thy sayings, And mightest overcome when thou art judged.

⁷For, behold, I was conceived in iniquities, And in sins did my mother conceive me.

⁸For, behold, thou lovest truth: Thou hast manifested to me the secret and hidden things of thy wisdom.

⁹Thou shalt sprinkle me with hyssop, and I shall be purified: Thou shalt wash me, and I shall be made whiter than snow.
