(Before It's News)
1 Have mercy on me, O God, according to thy steadfast love; according to thy abundant mercy blot out my transgressions.
2 Wash me thoroughly from my iniquity, and cleanse me from my sin!
3 For I know my transgressions, and my sin is ever before me.
4 Against thee, thee only, have I sinned, and done that which is evil in thy sight, so that thou art justified in thy sentence and blameless in thy judgment.
10 Create in me a clean heart, O God, and put a new and right spirit within me.
11 Cast me not away from thy presence, and take not thy holy Spirit from me.
15 O Lord, open thou my lips, and my mouth shall show forth thy praise.
