Psalms 51:5

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, perhaps (although elsewhere, i.e., in Psa 90:2, the idea of painfulness is kept entirely in the background) with reference to the decree, "with pain shalt thou bring forth children," Gen 3:16 (Kurtz); instead of הרתה אתי, with still more definite reference to that which precedes conception, the expression is יחמתני (for יחמתני, following the same interchange of vowel as in Gen 30:39; Jdg 5:28). The choice of the verb decides the question whether by עון and חטא is meant the guilt and sin of the child or of the parents. יחם (to burn with desire) has reference to that, in coition, which partakes of the animal, and may well awaken modest sensibilities in man, without עיון and חטא on that account characterizing birth and conception itself as sin; the meaning is merely, that his parents were sinful human begins, and that this sinful state (habitus) has operated upon his birth and even his conception, and from this point has passed over to him. What is thereby expressed is not so much any self-exculpation, as on the contrary a self-accusation which glances back to the ultimate ground of natural corruption. He is sinful מלּדה וּמהריון (Psa 58:4; Gen 8:21), is טמא מטּמא, an unclean one springing from an unclean (Job 14:4), flesh born of flesh. That man from his first beginning onwards, and that this beginning itself, is stained with sin; that the proneness to sin with its guilt and its corruption is propagated from parents to their children; and that consequently in the single actual sin the sin-pervaded nature of man, inasmuch as he all…

Though David penned this psalm upon a very particular occasion, yet, it is of as general use as any of David's psalms; it is the most eminent of the penitential psalms, and most expressive of the cares and desires of a repenting sinner. It is a pity indeed that in our devout addresses to God we should have any thing else to do than to praise God, for that is the work of heaven; but we make other work for ourselves by our own sins and follies: we must come to the throne of grace in the posture of penitents, to confess our sins and sue for the grace of God; and, if therein we would take with us words, we can nowhere find any more apposite than in this psalm, which is the record of David's repentance for his sin in the matter of Uriah, which was the greatest blemish upon his character: all the rest of his faults were nothing to this; it is said of him (Kg1 15:5), That "he turned not aside from the commandment of the Lord all the days of his life, save only in the matter of Uriah the Hittite." In this psalm, I. He confesses his sin (Psa 51:3-6). II. He prays earnestly for the pardon of his sin (Psa 51:1, Psa 51:2, Psa 51:7, Psa 51:9). III. For peace of conscience (Psa 51:8, Psa 51:12). IV. For grace to go and sin no more (Psa 51:10, Psa 51:11, Psa 51:14). V. For liberty of access to God (Psa 51:15). IV. He promises to do what he could for the good of the souls of others (Psa 51:13) and for the glory of God (Psa 51:16, Psa 51:17, Psa 51:19). And, lastly, concludes with a prayer for Zion and Jerusalem (Psa 51:18). Those whose consciences charge them with any gross sin should, with a believing regard to Jesus Christ, the Mediator, again and again pray over this psalm; nay, though we have not been guilty of adultery and murder, or any the like enormous crime, yet in singing it,…

51:5 I was born a sinner: The psalmist is not making excuses but is acknowledging the depth of his sinfulness. From the time we are conceived, we all share in the human condition of sinfulness.
