3:8 Jannes and Jambres. The names of these Egyptian magicians are not given in the Biblical account (Exodus 7:11), but are the traditional names handed down in extra-Biblical accounts. The book of Jasher says that Jannes and Jambres were sons of the false prophet Balaam.
3:8 resist the truth. The reason why the latter-day religious humanists and liberals can never “come to the knowledge of the truth” (II Timothy 3:7) is simply because they, like Pharaoh’s wise men, “resist the truth” when they hear it (note Romans 1:28), thus acquiring a “reprobate mind.”
