Exodus 7:11-13

11Then 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.

12For every man threw down his staff and they turned into serpents; but Aaron’s staff swallowed up their staffs.

13Yet Pharaoh’s heart was hardened and he would not listen to them, just as the Lord had said.
