11 However, Pharʹaoh summoned the wise men and the sorcerers, and the magic-practicing priests of Egypt+ also did the same thing with their magic.*+ 12 Each one threw down his rod, and they became big snakes; but Aaron’s rod swallowed up their rods.

20 Immediately Moses and Aaron did just as Jehovah had commanded. He lifted up the rod and struck the water that was in the Nile River before the eyes of Pharʹaoh and his servants, and all the water that was in the river was turned into blood.+

22 Nevertheless, the magic-practicing priests of Egypt did the same thing with their secret arts,+ so that Pharʹaoh’s heart continued to be obstinate, and he did not listen to them, just as Jehovah had said.+

8 Now in the way that Janʹnes and Jamʹbres opposed Moses, so these also go on opposing the truth. Such men are completely corrupted in mind, disapproved as regards the faith.
