Jeremiah 8:8

How do ye say, We are wise, and the Law of the Lord is with us? They prided themselves upon their possessing the Law, Romans 2:17; but this fact alone served rather to emphasize their dead orthodoxy, since they ignored the very teachings which they so emphatically proclaimed. Lo, certainly in vain made He it; the pen of the scribes is in vain, the false teachers, who spread their lies with word of mouth and pen, were spreading falsehood, even while they professed to be zealous for the truth. Their false pen converted the Law of God into a lie, just as the false teachers of all times have done.
