Title.—(RV) 'For the Chief Musician. A Psalm of David: when Nathan the prophet' came unto him, after he had gone in to Bathsheba.' It is impossible not to feel the general appropriateness of this Ps. to the occasion mentioned in the title, and there is no historic OT. figure except David to whom we can point as an illustration of the great sin and deep penitence which are the theme of the Ps. The theory that the speaker is the nation of Israel hardly accounts for the highly personal tone of the whole poem. At the same time, the affinity of the thought and language with the closing Chapter s of Isaiah (see especially on Psalms 51:11) favours the view that the writer lived during the exile, in which case he may well have chosen David's great transgression and its results as the subject of a 'dramatic lyric' On any supposition as to authorship and date Psalms 51:18-19 are to be regarded as a liturgical addition appended to the Ps. when it came to be used in the Temple services. Part of Psalms 51:4 is quoted (from LXX) in Romans 3:4.
Psalms 51:1-19
1 Have mercy upon me, O God, according to thy lovingkindness: 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.
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 conceivea 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.
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 rightb spirit within me.
11 Cast me not away from thy presence; and take not thy holy spirit from me.
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,c 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.
