Have mercy on me, O God, according to thy steadfast love;
according to thy abundant mercy blot out my transgressions.
Wash me thoroughly from my iniquity,
and cleanse me from my sin!
For I know my transgressions, and my sin is ever before me.
Behold, thou desirest truth in the inward being;
therefore teach me wisdom in my secret heart.
Purge me with hyssop, and I shall be clean;
wash me, and I shall be whiter than snow.
Fill me with joy and gladness;
