2 Timothy 3:8

‘And even as Jannes and Jambres withstood Moses, so do these also withstand the truth. Men corrupted in mind, reprobate concerning the faith.’

For these men who creep into women’s houses are like the magicians who opposed Moses in the days of the Pharaoh (Exodus 7:11, where the Jewish commentary, the Targum of Jonathan, mentions Jannes and Jambres; Exodus 8:7; Exodus 9:11). Just as those magicians/false religionists opposed and withstood Moses, so do these false teachers oppose and withstand the truth. They stand firm against the revelation of God’s power. And this is because their minds are corrupted, so that they have become spurious, ‘rejected after testing’, concerning the faith.
