2 Timothy 3:6-9 NIV

[6] They are the kind who worm their way into homes and gain control over gullible women, who are loaded down with sins and are swayed by all kinds of evil desires, [7] always learning but never able to come to a knowledge of the truth. [8] Just as Jannes and Jambres opposed Moses, so also these teachers oppose the truth. They are men of depraved minds, who, as far as the faith is concerned, are rejected. [9] But they will not get very far because, as in the case of those men, their folly will be clear to everyone.
