Jannes and Jambres

Boyd’s Bible Dictionary:

An Egyptian magician

Concise Bible Dictionary:

These are mentioned by Paul as having withstood Moses; to whom he compares those who by imitation were resisting the truth in the church (2 Tim. 3:88Now as Jannes and Jambres withstood Moses, so do these also resist the truth: men of corrupt minds, reprobate concerning the faith. (2 Timothy 3:8)). Jannes and Jambres were doubtless the leaders of the Egyptian magicians who imitated the first plagues before Pharaoh; but who, when it was a question of the creation of life, had to confess that the finger of God was there. The judgment of God fell upon them also, for they were smitten with the boils and blains. As their folly was manifest in contending with the God of Israel, so shall be the folly of those who oppose the truth.
