Have mercy upon me, O God,
        according to your lovingkindness;

 Wash me thoroughly from my iniquity,
        and cleanse me.

 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, 

 Renew a steadfast spirit within me.

 Restore to me the joy of Your salvation.

 You do not desire sacrifice,
        or else I would give it;

 You do not delight in burnt offering.

 The sacrifices of God are a broken spirit,

 A broken and contrite heart--
        these, O God, You will not despise.
