(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.
12 Restore to me the joy of thy salvation, and uphold me with a willing spirit.
15 O Lord, open thou my lips, and my mouth shall show forth thy praise.
