“Now as Iannes and Iambres withstood Moses, so do these also resist the trueth: men of corrupt mindes, reprobate concerning the faith.”
1611 King James Version (KJV)
3:8 Several ancient writers speak of Jannes and Jambres, as the chief of the Egyptian magicians. Men of corrupt minds - Impure notions and wicked inclinations. Void of judgment - Quite ignorant, as well as careless, of true, spiritual religion.
2Ti 3:8 As Jannes and Jambres withstood Moses. These were the traditional names of the Egyptian magicians who opposed Moses. See Ex 7:11. Paul adopts these names in referring to them. As these opposed Moses, so do the false teachers just described oppose the truth. These names are found in a Jewish Targum on Ex 7:11 22:11. Reprobate concerning the faith. Have abandoned the faith.
