Psalm 51:6-9

Behold, thou desirest truth in the inward parts: And in the hidden part thou shalt make me to know wisdom. Purge me with hyssop, and I shall be clean: Wash me, and I shall be whiter than snow. Make me to hear joy and gladness; That the bones which thou hast broken may rejoice. Hide thy face from my sins, And blot out all mine iniquities.
