Exodus 7:11-13

7:11 Then Pharaoh also summoned wise men and sorcerers, and the magicians of Egypt by their secret arts did the same thing. 7:12 Each man threw down his staff, and the staffs became snakes. But Aaron’s staff swallowed up their staffs. 7:13 Yet Pharaoh’s heart became hard, and he did not listen to them, just as the Lord had predicted.
