2 Timothy 3:8-9

Just as Jannes and Jambres [the court magicians of Egypt] opposed Moses, so these men also oppose the truth, men of depraved mind, unqualified and worthless [as teachers] in regard to the faith. [Ex 7:11] But they will not get very far, for their meaningless nonsense and ignorance will become obvious to everyone, as was that of Jannes and Jambres.
