9. “When Pharaoh speaks to you saying, ‘Prove yourselves with a miracle,’ then you are to say to Aaron, ‘Take your staff and cast it down before Pharaoh, so that it may become a serpent.’”
10. So Moses and Aaron went in to Pharaoh and did as Adonai had commanded. Aaron threw down his staff before Pharaoh and before his servants, and it became a serpent.
11. Then Pharaoh called for the wise men and the sorcerers, and they too, the magicians of Egypt, did the same with their secret arts.
12. For each man threw down his staff, and they became serpents. But Aaron’s staff swallowed up their staffs.
13. Yet Pharaoh’s heart was hardened. So he did not listen to them— just as Adonai had said.
14. Then Adonai said to Moses, “Pharaoh’s heart is stubborn; he refuses to let the people go.
15. Go to Pharaoh in the morning as he is coming out to the water, and stand ready to meet him by the bank of the Nile. Take the staff that was transformed into a serpent in your hand.
