For I know my sins [1] He now discovers his reason for imploring pardon with so much vehemency, and this was the painful disquietude which his sins caused him, and which could only be relieved by his obtaining reconciliation with God. This proves that his prayer did not proceed from dissimulation, as many will be found commending the grace of God in high terms, although, in reality, they care little about it, having never felt the bitterness of being exposed to his displeasure. David, on the contrary, declares that he is subjected by his sin to constant anguish of mind, and that it is this which imparts such an earnestness to his supplications. From his example we may learn who they are that can alone be said to seek reconciliation with God in a proper manner. They are such as have had their consciences wounded with a sense of sin, and who can find no rest until they have obtained assurance of his mercy. We will never seriously apply to God for pardon, until we have obtained such a view of our sins as inspires us with fear. The more easily satisfied we are under our sins, the more do we provoke God to punish them with severity, and if we really desire absolution from his hand, we must do more than confess our guilt in words; we must institute a rigid and formidable scrutiny into the character of our transgressions. David does not simply say that he will confess his sins to man, but declares that he has a deep inward feeling of them, such a feeling of them as filled him with the keenest anguish. His was a very different spirit from that of the hypocrite, who displays a complete indifference upon this subject, or when it intrudes upon him, endeavors to bury the recollection of it. He speaks of his sins in the plural number. His transgression, although it sprung from one root, was complicated, including, besides adultery, treachery and cruelty; nor was it one man only whom he had betrayed, but the whole army which had been summoned to the field in defense of the Church of God. He accordingly recognises many particular sins as wrapt up in it.
1 - As if he had said, "I confess and acknowledge that I have sinned, nor do I say as Cain did, I know not,' (Genesis 4:9.) What I formerly shamefully and foolishly excused and extenuated, I now acknowledge before thee and thy prophet, and the whole Church, in this penitential psalm." The verb is in the future, I will know or acknowledge, to intimate that he would continue to retain an humble sense of his guilt.
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 (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.
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.
For . . . before me--Conviction precedes forgiveness; and, as a gift of God, is a plea for it (2-Samuel 12:13; Psalm 32:5; 1-John 1:9).
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, Song 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 = בּדבריך; instead of בּשׁפטך, ἐν τῷ κρίνεσθαί σε = 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.
