51 Have mercy upon me, O God, according to thy lovingkindness: according unto the multitude of thy tender mercies blot out my transgressions.

² Wash me throughly from mine iniquity, and cleanse me from my sin.

⁶ Behold, thou desirest truth in the inward parts: and in the hidden part thou shalt make me to know wisdom.

⁷ Purge me with hyssop, and I shall be clean: wash me, and I shall be whiter than snow.
