Exodus 7:11, 22

Then Pharaoh called for the wise men [skilled in magic and omens] and the sorcerers [skilled in witchcraft], and they also, these magicians (soothsayer-priests) of Egypt, did the same with their secret arts and enchantments.

But the magicians of Egypt did the same by their secret arts and enchantments; so Pharaoh’s heart was hardened, and he did not listen to Moses and Aaron, just as the LORD had said.
