2 Timothy 3:8 in the King James Version
Now as Jannes and Jambres withstood Moses, so do these also resist the truth: men of corrupt minds, reprobate concerning the faith.
Context
7 always learning and never able to come to the knowledge of the truth.
8 Even as Jannes and Jambres opposed Moses, so these also oppose the truth, men corrupted in mind, who concerning the faith are rejected.
9 But they will proceed no further. For their folly will be evident to all men, as theirs also came to be.
