Kehillah in Rome 7:7

7 What then shall we say? That the Torah is considered as chet (sin)? Chas v’shalom! Nevertheless, I would not have experienced chet (sin) except through the Torah; for I would not have known chamdanut (covetousness, greediness) if the Torah had not said, LO TACHMOD ("Thou shalt not covet" SHEMOT 20:17).
