Create unto me a clean heart, O God; and a firm spirit renew thou within me.

Salmos 51:10

Wash yourselves, make yourselves clean; put away the evil of your deeds from before my eyes; cease to do evil;

Isaías 1:16

To the chief musician, a psalm of David, When Nathan the prophet came unto him, after he had gone in unto Bath–sheba’. Be gracious unto me, O God, according to thy kindness: according to the greatness of thy mercies blot out my transgressions.

Wash me thoroughly from my iniquity, and cleanse me from my sin.

Salmos 51:1,2
