according unto the multitude of thy tender mercies blot out my transgressions.
2 Wash me throughly from mine iniquity,
and cleanse me from my sin.
(New covenant, God says: Heb. 8 ... 10 For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts:and I will be to them a God, and they shall be to me a people:11 And they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord:for all shall know me, from the least to the greatest. 12 For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more.)
3 For I acknowledge my transgressions:
and my sin is ever before me.
4 Against thee, thee only, have I sinned,
and done this evil in thy sight:
that thou mightest be justified when thou speakest,
and be clear when thou judgest.
5 Behold, I was shapen in iniquity;
and in sin did my mother conceive me.
6 Behold, thou desirest truth in the inward parts:
and in the hidden part thou shalt make me to know wisdom.
7 Purge me with hyssop, and I shall be clean:
wash me, and I shall be whiter than snow.
(Jesus said ... John 15:3 Now ye are clean through the word which I have spoken unto you.)
8 Make me to hear joy and gladness;
that the bones which thou hast broken may rejoice.
9 Hide thy face from my sins,
and blot out all mine iniquities.
10 Create in me a clean heart, O God;
and renew a right spirit within me.
(Prayer of David)
11 Cast me not away from thy presence;
and take not thy holy spirit from me.
(God had removed HIS Holy Spirit from Saul and had given HIS Holy Spirit to David. David had sinned greatly by having Uriah killed so he could have Bathsheba, Uriah's wife, openly as his wife. Though Bathsheba was pregnant by David at the time David sent Uriah to the front lines to have him die in battle.)
12 Restore unto me the joy of thy salvation;
and uphold me with thy free spirit.
13 Then will I teach transgressors thy ways;
and sinners shall be converted unto thee.
14 Deliver me from bloodguiltiness, O God, thou God of my salvation:
and my tongue shall sing aloud of thy righteousness.
15 O Lord, open thou my lips;
and my mouth shall shew forth thy praise.
16 For thou desirest not sacrifice; else would I give it:
thou delightest not in burnt offering.
17 The sacrifices of God are a broken spirit:
a broken and a contrite heart, O God, thou wilt not despise.
18 Do good in thy good pleasure unto Zion:
build thou the walls of Jerusalem.
19 Then shalt thou be pleased with the sacrifices of righteousness, with burnt offering and whole burnt offering:
then shall they offer bullocks upon thine altar.
