TSK · Exodus 9:11

Then Pharaoh also summoned wise men and sorcerers, and the magicians of Egypt by their secret arts did the same thing.

When the magicians attempted to bring forth gnats by their secret arts, they could not. So there were gnats on people and on animals.

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.
