For thy name's sake, O Lord, pardon mine iniquity,.... Which to do is one of the promises and blessings of the covenant. The psalmist may have reference to his sin with Bathsheba, as Kimchi observes; since it was foretold to him, that, on account of that sin, evil should arise to him out of his own house, Sa2 12:11; meaning that his son should rise up in rebellion against him; which was now the case, and which, no doubt, brought afresh this sin to his mind; and the guilt of it lay heavy upon his conscience; and therefore he prays for an application of pardoning grace and mercy; or he may have respect to original sin, the sin of his nature, which so easily beset him; the loathsome disease his loins were filled with; the law in his members warring against the law of his mind; and which a view of every actual sin led him to the consideration and acknowledgment of, as did that now mentioned, Psa 51:4; or, "iniquity" may be put for "iniquities", and the sense be, that he desired a manifestation of the pardon of all his sins; for when God forgives sin, he forgives all iniquities: and David here prays for pardon in a way of mercy, and upon the foot of satisfaction; for he prays that God would "mercifully pardon" (a), as the word signifies; or, according to his tender mercies, blot out his transgressions, and cleanse him from his sins; or that he would be "propitious" (b) to him; or forgive him in a propitiatory way, or through the propitiation of Christ, whom God had set forth in his purposes and promises to be the propitiation for the remission of sins; and therefore he entreats this favour "for his name's sake"; not for his own merits and good works, but for the Lord's sake, for his mercy's sake, or for his Son's sake; see Isa 43:25; compared with Eph 5:32. The argument or reason he urges is, for it is great; being committed against the great God, against great light and knowledge, and attended with very aggravating circumstances; or "much" (c), he being guilty of many sins; his sins were great, both as to quality and quantity: this seems to be rather a reason against than a reason for the pardon of sin; it denotes the sense the psalmist had of his iniquity, and his importunity for the pardon of it; just as a person, sensible of the violence and malignity of his disease, entreats the physician with the greater eagerness and importunity to do his utmost for him; see Psa 41:4; or the words may be rendered, "though it is great" (d); so Aben Ezra understands them; "though it is so very heinous and provoking, yet since forgiveness is with thee, and thou hast promised it in covenant, and hast proclaimed thy name, a God gracious and merciful, pardon it;'' unless the words are to be connected, as they are by some Jewish (e) interpreters, with the phrase "thy name's sake, for it is great"; that is, thy name is great, and that it may appear to be so, as it is proclaimed, forgive mine iniquity. (a) "mercifully pardon"; so Ainsworth. (b) Sept. "propitiaberis", V. L. "propitius esto", Musculus. (c) "multum", V. L. "multa", Pagninus, Montanus, Tigurine version.
