Exodus 7:10-12

New Revised Standard Version Catholic Edition

¹⁰ So Moses and Aaron went to Pharaoh and did as the Lord had commanded; Aaron threw down his staff before Pharaoh and his officials, and it became a snake. 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 Each one threw down his staff, and they became snakes; but Aaron’s staff swallowed up theirs.
