Have mercy opon me, O God - This is the utterance of a full heart; a heart crushed and broken by the consciousness of sin. The psalmist had been made to see his great guilt; and his first act is to cry out for mercy. There is no attempt to excuse his sin, or to apologise for it; there is no effort to vindicate his conduct; there is no complaint of the righteousness of that holy law which condemned him. It was "guilt" that was before his mind; guilt only; deep and dreadful guilt. The appeal properly expresses the state of a mind that is overwhelmed at the remembrance of crime, and that comes with earnestness to God to plead for pardon. The only hope of a sinner when crushed with the consciousness of sin is the mercy of God; and the plea for that mercy will be urged in the most earnest and impassioned language that the mind can employ. "Accordingly to thy Iovingkindness." On the meaning of the word used here, see the notes at Psalm 36:7.

(a) The "ground" of his hope was the compassion of God:

(b) the "measure" of that hope was His boundless beneficence; or, in other words, he felt that there was need of "all" the compassion of a God.

His sin was so great, his offence was so aggravated, that he could have no hope but in a Being of infinite compassion, and he felt that the need of mercy in his case could be measured and covered "only" by that infinite compassion.

According unto the multitude of thy tender mercies - The same idea occurs here also. The psalmist fixed his eye on the "vastness" of the divine mercy; on the numberless "acts" of that mercy toward the guilty; here he found his hope, and here alone. Every instance of extraordinary mercy which had occurred in the world furnished him now with an argument in his appeal to God; was an encouragement to him "in" that appeal; was a ground of hope that his appeal would not be rejected. So to us: every instance in which a great sinner has been forgiven is evidence that we may be forgiven also, and is an encouragement to us to come to God for pardon. See the notes at 1 Timothy 1:16.

Blot out my transgressions - In allusion to an account that is kept, or a charge made, when such an account is wiped away, erased, or blotted out. Compare Exodus 32:32-33; see the notes at Isaiah 43:25; notes at Isaiah 44:22; notes at Colossians 2:14. Never was a more earnest appeal made by a sinner than that which is made in this verse; never was there a more sincere cry for mercy. It shows us where we should "begin" in our prayers when we are pressed down with the consciousness of sin - with a cry for "mercy," and not an appeal to "justice;" it shows us what is to be the "ground" and the "measure" of our hope - the mere compassion of an infinitely benevolent God; it shows us the place which we must take, and the argument on which we must rely - a place among sinners, and an argument that God has been merciful to great sinners, and that therefore he may be merciful to us.

Have mercy upon me, O God - Without mercy I am totally, finally ruined and undone.

According to thy loving-kindness - Mark the gradation in the sense of these three words, Have Mercy on me, חנני chonneni; thy Loving-Kindness, חסדך chasdecha; - thy Tender Mercies, רחמיך rachameycha, here used to express the Divine compassion. The propriety of the order in which they are placed deserves particular observation.

The first, rendered have mercy or pity, denotes that kind of affection which is expressed by moaning over an object we love and pity; that natural affection and tenderness which even the brute creation show to their young by the several noises they respectively make over them.

The second, rendered loving-kindness, denotes a strong proneness, a ready, large, and liberal disposition, to goodness and compassion, powerfully prompting to all instances of kindness and bounty; flowing as freely as waters from a perpetual fountain. This denotes a higher degree of goodness than the former.

The third, rendered tender mercies, denotes what the Greeks called splagcnizesqai, that most tender pity which we signify by the moving of the heart and bowels, which argues the highest degree of compassion of which nature is susceptible. See Chandler.

Blot out my transgressions - מחה mecheh, wipe out. There is a reference here to an indictment: the psalmist knows what it contains; he pleads guilty, but begs that the writing may be defaced; that a proper fluid may be applied to the parchment, to discharge the ink, that no record of it may ever appear against him: and this only the mercy, loving-kindness, and tender compassions of the Lord can do.

Have mercy upon me, O God,.... David, under a sense of sin, does not run away from God, but applies unto him, and casts himself at his feet, and upon his mercy; which shows the view he had of his miserable condition, and that he saw there was mercy in God, which gave him hope; and upon his bended knees, and in the exercise of faith, he asks for it;

according to thy lovingkindness; not according to his merits, nor according to the general mercy of God, which carnal men rely upon; but according to his everlasting and unchangeable love in Christ; from which as the source, and through whom as the medium, special mercy comes to the children of men. The acts of special mercy are according to the sovereign will of God: he is not moved to mercy neither by the merits nor misery of men, but by his free grace and favour; it is love that sets mercy to work: this is a most glaring gleam of Gospel light, which none of the inspired writers besides, except the Apostle Paul, saw, Ephesians 2:4;

according unto the multitude of thy tender mercies blot out my transgressions; for his sin was complicated, attended with many others; and, besides, upon a view of this, he was led to observe all his other sins; and particularly the corruption of his nature, his original sin, which he mentions, Psalm 51:5. These he desires might be "blotted out"; out of the book of account, out of God's debt book; that they might not stand against him, being debts he was not able to pay or make satisfaction for; and out of the table of his own heart and conscience, where they were ever before him, and seemed to be engraven; that they might be caused to pass from him, and he might have no more conscience of them; or that they might be blotted out, as a cloud by the clear shining of the sun of righteousness, with the healing of pardoning grace in his wings; or that they might be wiped away, as any faith is wiped from any person or thing: and all this "according to the multitude of his tender mercies". The mercy of God is plenteous and abundant; he is rich in it, and various are the instances of it; and it is exceeding tender, like that of a father to his children, or like that of a mother to the son of her womb; and from this abundant and tender mercy springs the forgiveness of sin, Luke 1:77. The psalmist makes mention of the multitude of the mercies of God, because of the multitude of his sins, which required a multitude of mercy to forgive, and to encourage his hope of it.

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 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.

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.

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.

Psalm 51:1

"Have mercy upon me, O God." He appeals at once to the mercy of God, even before he mentions his sin. The sight of mercy is good for eyes that are sore with penitential weeping. Pardon of sin must ever be an act of pure mercy, and therefore to that attribute the awakened sinner flies. "According to thy lovingkindness." Act, O Lord, like thyself; give mercy like thy mercy. Show mercy such as is congruous with thy grace.

Prayer for the remission of sin. Concerning the interchangeable names for sin, vid., on Psalm 32:1. Although the primary occasion of the Psalm is the sin of adultery, still David says פּשׁעי, not merely because many other sins were developed out of it, as his guilt of blood in the case of Uriah, the scandal put into the mouths of the enemies of Jahve, and his self-delusion, which lasted almost a whole year; but also because each solitary sin, the more it is perceived in its fundamental character and, as it were, microscopically discerned, all the more does it appear as a manifold and entangled skein of sins, and stands forth in a still more intimate and terrible relation, as of cause and effect, to the whole corrupt and degenerated condition in which the sinner finds himself. In מחה sins are conceived of as a cumulative debt (according to Isaiah 44:22, cf. Isaiah 43:25, like a thick, dark cloud) written down (Jeremiah 17:1) against the time of the payment by punishment. In כּבּסני (from כּבּס, πλύνειν, to wash by rubbing and kneading up, distinguished from רחץ, λούειν, to wash by rinsing) iniquity is conceived of as deeply ingrained dirt. In טהרני, the usual word for a declarative and de facto making clean, sin is conceived of as a leprosy, Leviticus 13:6, Leviticus 13:34. the Kerמ runs הרב כּבּסני (imperat. Hiph., like הרף, Psalm 37:8), "make great or much, wash me," i.e., (according to Ges. ֗142, 3, b) wash me altogether, penitus et totum, which is the same as is expressed by the Chethמb הרבּה (prop. multum faciendo equals multum, prorsus, Ges. ֗131, 2). In כּרב (Isaiah 63:7) and הרב is expressed the depth of the consciousness of sin; profunda enim malitia, as Martin Geier observes, insolitam raramque gratiam postulat.

<{a} came unto him, after he had gone in to Bathsheba.>> Have mercy upon me, O God, {b} according to thy lovingkindness: according unto the multitude of thy tender mercies blot out my transgressions.

(a) To reprove him, because he had committed horrible sins, and lain in the same without repentance more then a whole year.

(b) As his sins were many and great, so he requires that God would give him the feeling of his excellent and abundant mercies.

This Psalm must ever be, in its successive steps, the mould of the experience of a sinning saint who comes back to full communion and service. The steps are:

(1) sin thoroughly judged before God (vs. 1-6);

(2) forgiveness and cleansing through the blood (v. 7.f.c.)

(3) cleansing (v. 7,1,c, to 10.) Cf Jn 13:4-10 Eph 5:26 1Jn 1:9.

(4) Spirit-filled for joy and power (vs. 11,12);

(5) service (v. 13);

(6) worship (vs 14-17);

(7) the restored saint in fellowship with God, not about self, but about the blessing of Zion. Personally, it was David's pathway to restored communion after his sin with Bathsheba. Dispensationally, it will be the pathway of returning Israel. Dt 30:1-10.

PSALM 51

Ps 51:1-19. On the occasion, compare 2Sa 11:12. The Psalm illustrates true repentance, in which are comprised conviction, confession, sorrow, prayer for mercy, and purposes of amendment, and it is accompanied by a lively faith.

1-4. A plea for mercy is a confession of guilt.

blot out-as from a register.

transgressions-literally, "rebellions" (Ps 19:13; 32:1).

51:1-6 David, being convinced of his sin, poured out his soul to God in prayer for mercy and grace. Whither should backsliding children return, but to the Lord their God, who alone can heal them? he drew up, by Divine teaching, an account of the workings of his heart toward God. Those that truly repent of their sins, will not be ashamed to own their repentance. Also, he instructs others what to do, and what to say. David had not only done much, but suffered much in the cause of God; yet he flees to God's infinite mercy, and depends upon that alone for pardon and peace. He begs the pardon of sin. The blood of Christ, sprinkled upon the conscience, blots out the transgression, and, having reconciled us to God, reconciles us to ourselves. The believer longs to have the whole debt of his sins blotted out, and every stain cleansed; he would be thoroughly washed from all his sins; but the hypocrite always has some secret reserve, and would have some favorite lust spared. David had such a deep sense of his sin, that he was continually thinking of it, with sorrow and shame. His sin was committed against God, whose truth we deny by wilful sin; with him we deal deceitfully. And the truly penitent will ever trace back the streams of actual sin to the fountain of original depravity. He confesses his original corruption. This is that foolishness which is bound in the heart of a child, that proneness to evil, and that backwardness to good, which is the burden of the regenerate, and the ruin of the unregenerate. He is encouraged, in his repentance, to hope that God would graciously accept him. Thou desirest truth in the inward part; to this God looks, in a returning sinner. Where there is truth, God will give wisdom. Those who sincerely endeavour to do their duty shall be taught their duty; but they will expect good only from Divine grace overcoming their corrupt nature.
