"Purge me with hyssop and I shall be clean; wash me and I shall be whiter than snow. Make me hear joy and gladness, that the bones you have broken my rejoice. Hide Your face from my sins and blot out all my iniquities. Create in me a clean heart, O God, and renew a steadfast spirit in me. Do not cast me away from Your presence, and do not take Your Holy Spirit from me. Restore unto me the joy of my salvation and uphold me by Your generous Spirit. Then I will teach transgressors your ways and sinners shall be converted to You." Psalm 51:7-13
