(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.
16 For thou hast no delight in sacrifice; were I to give a burnt offering, thou wouldst not be pleased.
17 The sacrifice acceptable to God is a broken spirit; a broken and contrite heart, O God, thou wilt not despise.
