Exodus 7:11-13

Revised Standard Version

¹¹ Then Pharaoh summoned the wise men and the sorcerers; and they also, the magicians of Egypt, did the same by their secret arts. ¹² For every man cast down his rod, and they became serpents. But Aaron’s rod swallowed up their rods. ¹³ Still Pharaoh’s heart was hardened, and he would not listen to them; as the Lord had said.
