Wash me thoroughly from mine iniquity, and cleanse me from my sin. . . . Purge me with hyssop, and I shall be clean: wash me, and I shall be whiter than snow. . . . .Create in me a clean heart, O God; and renew a right spirit within me. . . . Restore unto me the joy of Thy salvation. . . . The sacrifices of God are a broken spirit: a broken and a contrite heart, O God, thou wilt not despise.
Prayer of David From Psalm 51
