The Lord said to Moses and Aaron,
"When Pharaoh tells you: Perform a miracle, tell Aaron: Take your staff and throw it down before Pharaoh. It will become a serpent."
So Moses and Aaron went in to Pharaoh and did just as the Lord had commanded. Aaron threw down his staff before Pharaoh and his officials, and it became a serpent.
But then Pharaoh called the wise men and sorcerers-the magicians of Egypt, and they also did the same thing by their occult practices.
Each one threw down his staff, and it became a serpent. But Aaron's staff swallowed their staffs.
However, Pharaoh's heart hardened, and he did not listen to them, as the Lord had said.
