Psalms 51:14

The third part now begins with a doubly urgent prayer. The invocation of God by the name Elohim is here made more urgent by the addition of אלהי תשׁוּעתי; inasmuch as the prayers for justification and for renewing blend together in the "deliver me." David does not seek to lessen his guilt; he calls it in דּמים by its right name, - a word which signifies blood violently shed, and then also a deed of blood and blood-guiltiness (Psa 9:13; Psa 106:38, and frequently). We have also met with הצּיל construed with מן of the sin in Psa 39:9. He had given Uriah over to death in order to possess himself of Bathsheba. And the accusation of his conscience spoke not merely of adultery, but also of murder. Nevertheless the consciousness of sin no longer smites him to the earth, Mercy has lifted him up; he prays only that she would complete her work in him, then shall his tongue exultingly praise (רנּן with an accusative of the object, as in Psa 59:17) God's righteousness, which, in accordance with the promise, takes the sinner under its protection. But in order to perform what he vowed he would do under such circumstances, he likewise needs grace, and prays, therefore, for a joyous opening of his mouth. In sacrifices God delighteth not (Psa 40:7, cf. Isa 1:11), otherwise he would bring some (ואתּנה, darem, sc. si velles, vid., on Psa 40:6); whole-burnt-offerings God doth not desire: the sacrifices that are well-pleasing to Him and most beloved by Him, in comparison with which the flesh and the dead work of the עולות and the זבחים (שׁלמים) is altogether worthless, are thankfulness (Psa 50:23) out of the fulness of a penitent and lowly heart. There is here, directly at least, no reference to the spiritual antitype of the sin-offering, which is never called זבה. The inward part of a man…

I. David prays against the guilt of sin, and prays for the grace of God, enforcing both petitions from a plea taken from the glory of God, which he promises with thankfulness to show forth. 1. He prays against the guilt of sin, that he might be delivered from that, and promises that then he would praise God, Psa 51:14. The particular sin he prays against is blood-guiltiness, the sin he had now been guilty of, having slain Uriah with the sword of the children of Ammon. Hitherto perhaps he had stopped the mouth of conscience with that frivolous excuse, that he did not kill him himself; but now he was convinced that he was the murderer, and, hearing the blood cry to God for vengeance, he cries to God for mercy: "Deliver me from blood-guiltiness; let me not lie under the guilt of this kind which I have contracted, but let it be pardoned to me, and let me never be left to myself to contract the like guilt again." Note, It concerns us all to pray earnestly against the guilt of blood. In this prayer he eyes God as the God of salvation. Note, Those to whom God is the God of salvation he will deliver from guilt; for the salvation he is the God of is salvation from sin. We may therefore plead this with him, "Lord, thou art the God of my salvation, therefore deliver me from the dominion of sin." He promises that, if God would deliver him, his tongue should sing aloud of his righteousness; God should have the glory both of pardoning mercy and of preventing grace. God's righteousness is often put for his grace, especially in the great business of justification and sanctification. This he would comfort himself in and therefore sing of; and this he would endeavour both to acquaint and to affect others with; he would sing aloud of it. This all those should do that have had the benefit…

51:14 shedding blood: This idiom includes any injustice, not just homicide (9:12; 58:10; see 2 Sam 11:14-26; cp. Isa 1:15-17).
