Exodus 7:9-11

New Revised Standard Version, Anglicised Catholic Edition

⁹ ‘When Pharaoh says to you, “Perform a wonder”, then you shall say to Aaron, “Take your staff and throw it down before Pharaoh, and it will become a snake.”’ 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.
