Romans 7:7, 12-13

What shall we say then? Is the law sin? God forbid. Howbeit, I had not known sin, except through the law: for I had not known coveting, except the law had said, Thou shalt not covet

So that the law is holy, and the commandment holy, and righteous, and good. Did then that which is good become death unto me? God forbid. But sin, that it might be shown to be sin, by working death to me through that which is good;—that through the commandment sin might become exceeding sinful.
