2 Timothy 3:6-9
6 For among them are those who creep into households and capture weak women, burdened with sins and led astray by various passions, 7 always learning and never able to arrive at a knowledge of the truth. 8 Just as Jannes and Jambres opposed Moses, so these men also oppose the truth, men corrupted in mind and disqualified regarding the faith. 9 But they will not get very far, for their folly will be plain to all, as was that of those two men. (ESV)
