TSK · Exodus 8:7

But the magicians of Egypt did the same by their secret arts, and so Pharaoh’s heart remained hard, and he refused to listen to Moses and Aaron– just as the LORD had predicted.

For false messiahs and false prophets will appear and perform great signs and wonders to deceive, if possible, even the elect.

And just as Jannes and Jambres opposed Moses, so these people– who have warped minds and are disqualified in the faith– also oppose the truth.
