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 Psa 51:6 is applied by Paul (Rom 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, Gen 38:17, in this instance for the sake of similarity of sound[1] 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 Jer 2:9 lxx, cf. Mat 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.
Verses 5-6
David here confesses his hereditary sin as the root of his actual sin. The declaration moves backwards from his birth to conception, it consequently penetrates even to the most remote point of life's beginning. חוללתּי stands instead of נולדתּי,
