(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!
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.
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.
