Psalms 51

Psalms 51 14

My Notes Authors Matthew Henry - Commentary on the Whole Bible 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, v. 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 of it, and owe their all to it. 2. He prays for the grace of God and promises to improve that grace to his glory (v. 15): “O Lord! open thou my lips, not only that I may teach and instruct sinners” (which the best preacher cannot do to any purpose unless God give him the opening of the mouth, and the tongue of the learned), “but that my mouth may show forth thy praise, not only that I may have abundant matter for praise, but a heart enlarged in praise.” Guilt had closed his lips, had gone near to stop the mouth of prayer; he could not for shame, he could not for fear, come into the presence of that God whom he knew he had offended, much less speak to him; his heart condemned him, and therefore he had little confidence towards God. It cast a damp particularly upon his praises; when he had lost the joys of his salvation his harp was hung upon the willow-trees; therefore he prays, “Lord, open my life, put my heart in tune for praise again.” To those that are tongue-tied by reason of guilt the assurance of the forgiveness of their sins says effectually, Ephphatha—Be opened; and, when the lips are opened, what should they speak but the praises of God, as Zacharias did? Luke i. 64.

Psalms 51 7

My Notes Authors Matthew Henry - Commentary on the Whole Bible I. See here what David prays for. Many excellent petitions he here puts up, to which if we do but add, “for Christ’s sake,” they are as evangelical as any other. He prays that God would cleanse him from his sins and the defilement he had contracted by them (v. 7): “Purge me with hyssop; that is, pardon my sins, and let me know that they are pardoned, that I may be restored to those privileges which by sin I have forfeited and lost.” The expression here alludes to a ceremonial distinction, that of cleansing the leper, or those that were unclean by the touch of a body by sprinkling water, or blood, or both upon them with a bunch of hyssop, by which they were, at length, discharged from the restraints they were laid under by their pollution. “Lord, let me be as well assured of my restoration to thy favour, and to the privilege of communion with thee, as they were thereby assured of their re-admission to their former privileges.” But it is founded upon gospel-grace: Purge me with hyssop, that is, with the blood of Christ applied to my soul by a lively faith, as water of purification was sprinkled with a bunch of hyssop. It is the blood of Christ (which is therefore called _the blood of sprinkling, _Heb. xii. 24), that purges the conscience from dead works, from that guilt of sin and dread of God which shut us out of communion with him, as the touch of a dead body, under the law, shut a man out from the courts of God’s house. If this blood of Christ, which cleanses from all sin, cleanse us from our sin, then we shall be clean indeed, Heb. x. 2. If we be washed in this fountain opened, we shall be whiter than snow, not only acquitted but accepted; so those are that are justified. Isa. i. 18, Though your sins have been as scarlet, they shall be white as snow.
