Exodus 7:10-12

Revised Standard Version

¹⁰ So Moses and Aaron went to Pharaoh and did as the Lord commanded; Aaron cast down his rod before Pharaoh and his servants, and it became a serpent. 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.
