Because the law worketh wrath
Not the wrath of man, though that is sometimes stirred up through the prohibitions of the law, to which the carnal mind of man is enmity, but the wrath of God the law is so far from justifying sinners, that it curses and condemns them; and when it comes into the heart and is let into the conscience of a sinner, it fills with terrible apprehensions of the wrath of God, and a fearful looking for of his judgment and fiery indignation:
for where no law is, there is no transgression;
(hrybe alw hwum al) (wnyav) F18; a sort of a proverbial expression: had the law of Moses not been given, there was the law of nature which sin is a transgression of; but the law of Moses was added for the better discovery and detection of sin, which would not have been so manifest without it, and which may be the apostle's sense; that where there is no law, there is no knowledge of any transgression; and so the Ethiopic version reads the words, "if the law had not come, there would have been none who would have known sin"; but the law is come, and there is a law by which is the knowledge of sin, and therefore no man can be justified by it; since that convinces him of sin, and fills him with a sense of divine wrath on account of it.
F18 Caphtor, fol. 10. 1.
