For I will declare mine iniquity,.... Either to men, to ease his mind, justify God in his proceedings with him, and for their caution and admonition: or rather to God, against whom he had sinned, and who only could pardon him; with a view to which he was determined to make a free and open confession of it before him: I will be sorry for my sin, or "careful" (p) about it; that is, how he committed it for the future: true repentance for sin produces a carefulness to abstain from all appearance of it; see Co2 7:10. (p) "solicitus ero", Montanus; so Junius & Tremellius, Piscator, Gejerus, Michaelis, Ainsworth.
