Romans 7:7, 12-13

What shall we say then? Is the Law sin? Certainly not! On the contrary, if it had not been for the Law, I would not have recognized sin. For I would not have known [for example] about coveting [what belongs to another, and would have had no sense of guilt] if the Law had not [repeatedly] said, “YOU SHALL NOT COVET.” [Ex 20:17; Deut 5:21]

So then, the Law is holy, and the commandment is holy and righteous and good. Did that which is good [the Law], then become death to me? Certainly not! But sin, in order that it might be revealed as sin, was producing death in me by [using] this good thing [as a weapon], so that through the commandment sin would become exceedingly sinful.
