For I acknowledge my transgressions - literally, I know, or make known. That is, he knew that he was a sinner, and he did not seek to cloak or conceal that fact. He came with the knowledge of it himself; he was willing to make acknowledgment of it before God. There was no attempt to conceal it; to excuse it. Compare the notes at Psalm 32:5. The word ""for"" does not imply that he referred to his willingness to confess his sins as an act of merit, but it indicates a state of mind which was necessary to forgiveness, and without which he could not hope for pardon.

And my sin is ever before me - That is, It is now constantly before my mind. It had not been so until Nathan brought it vividly to his recollection (2 Samuel 12:1 ff); but after that it was continually in his view. He could not turn his mind from it. The memory of his guilt followed him; it pressed upon him; it haunted him. It was no wonder that this was so. The only ground of wonder in the case is that it did not occur "before" Nathan made that solemn appeal to him, or that he could have been for a moment insensible to the greatness of his crime. The whole transaction, however, shows that people "may" be guilty of enormous sins, and have for a long time no sense of their criminality; but that "when" the consciousness of guilt is made to come home to the soul, nothing will calm it down. Everything reminds the soul of it; and nothing will drive away its recollection. In such a state the sinner has no refuge - no hope of permanent peace - but in the mercy of God.

For I acknowledge my transgressions - I know, I feel, I confess that I have sinned.

My sin is ever before me - A true, deep, and unsophisticated mark of a genuine penitent. Wherever he turns his face, he sees his sin, and through it the eye of an angry God.

For I acknowledge my transgressions,.... Before God and man. Acknowledgment of sin is what the Lord requires, and promises forgiveness upon, and therefore is used here as a plea for it; and moreover the psalmist had done so before, and had succeeded in this way, which must encourage him to take the same course again; see Psalm 32:5;

and my sin is ever before me; staring him in the face; gnawing upon his conscience, and filling him with remorse and distress; so that his life was a burden to him: for though God had put away sin out of his own sight, so that he would not condemn him for it, and he should not die; notwithstanding as yet it was not caused to pass from David, or the guilt of it removed from his conscience.

Substantiation of the prayer by the consideration, that his sense of sin is more than superficial, and that he is ready to make a penitential confession. True penitence is not a dead knowledge of sin committed, but a living sensitive consciousness of it (Isaiah 59:12), to which it is ever present as a matter and ground of unrest and pain. This penitential sorrow, which pervades the whole man, is, it is true, no merit that wins mercy or favour, but it is the condition, without which it is impossible for any manifestation of favour to take place. Such true consciousness of sin contemplates sin, of whatever kind it may be, directly as sin against God, and in its ultimate ground as sin against Him alone (חטא with ל of the person sinned against, Isaiah 42:24; Micah 7:9); for every relation in which man stands to his fellow-men, and to created things in general, is but the manifest form of his fundamental relationship to God; and sin is "that which is evil in the eyes of God" (Isaiah 65:12; Isaiah 66:4), it is contradiction to the will of God, the sole and highest Lawgiver and Judge. Thus it is, as David confesses, with regard to his sin, in order that... This למען must not be weakened by understanding it to refer to the result instead of to the aim or purpose. If, however, it is intended to express intention, it follows close upon the moral relationship of man to God expressed in לך לבדּך and הרע בּעיניך, - a relationship, the aim of which is, that God, when He now condemns the sinner, may appear as the just and holy One, who, as the sinner is obliged himself to acknowledge, cannot do otherwise than pronounce a condemnatory decision concerning him. When sin becomes manifest to a man as such, he must himself say Amen to the divine sentence, just as David does to that passed upon him by Nathan. And it is just the nature of penitence so to confess one's self to be in the wrong in order that God may be in the right and gain His cause. If, however, the sinner's self-accusation justifies the divine righteousness or justice, just as, on the other hand, all self-justification on the part of the sinner (which, however, sooner or later will be undeceived) accuses God of unrighteousness or injustice (Job 40:8): then all human sin must in the end tend towards the glorifying of God. In this sense Psalm 51:6 is applied by Paul (Romans 3:4), inasmuch as he regards what is here written in the Psalter - ὅπως ἂν δικαιωθῇς ἐν τοῖς λόγοις σου, καὶ νικῃσεες ἐν τῷ κρίνεσθαί σε (lxx) - as the goal towards which the whole history of Israel tends. Instead of בּדברך (infin. like שׁלחך, Genesis 38:17, in this instance for the sake of similarity of sound

(Note: Cf. the following forms, chosen on account of their accord: - נשׂוּי, Psalm 32:1; הנדּף, Psalm 68:3; צאינה, Sol 3:11; שׁתות, Isaiah 22:13; ממחים, ib. Psalm 25:6; הלּוט, ib. Psalm 25:7.)

instead of the otherwise usual form דּבּר), in Thy speaking, the lxx renders ἐν τοῖς λόγοις σου equals בּדבריך; instead of בּשׁפטך, ἐν τῷ κρίνεσθαί σε equals בּהשּׁפטך (infin. Niph.), provided κρίνεσθαι is intended as passive and not (as in Jeremiah 2:9 lxx, cf. Matthew 5:40) as middle. The thought remains essentially unchanged by the side of these deviations; and even the taking of the verb זכה, to be clean, pure, in the Syriac signification νικᾶν, does not alter it. That God may be justified in His decisive speaking and judging; that He, the Judge, may gain His cause in opposition to all human judgment, towards this tends David's confession of sin, towards this tends all human history, and more especially the history of Israel.

For I {d} acknowledge my transgressions: and my sin is ever before me.

(d) My conscience accuses me so, that I can have no rest till I am reconciled.

3. For . before me-Conviction precedes forgiveness; and, as a gift of God, is a plea for it (2Sa 12:13; Ps 32:5; 1Jo 1:9).

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.
