2 Timothy 3:7-9

New Revised Standard Version Catholic Edition

⁷ who are always being instructed and can never arrive at a knowledge of the truth. ⁸ As Jannes and Jambres opposed Moses, so these people, of corrupt mind and counterfeit faith, also oppose the truth. ⁹ But they will not make much progress, because, as in the case of those two men,^[a] their folly will become plain to everyone.
