8The LORD said to Moses and Aaron,
9“When Pharaoh tells you, ‘Perform a miracle,’ you are to say to Aaron, ‘Take your staff and throw it down before Pharaoh,’ and it will become a serpent.”
10So Moses and Aaron went to Pharaoh and did just as the LORD had commanded. Aaron threw his staff down before Pharaoh and his officials, and it became a serpent.
11But Pharaoh called the wise men and sorcerers and magicians of Egypt, and they also did the same things by their magic arts.
12Each one threw down his staff, and it became a serpent. But Aaron’s staff swallowed up the other staffs.
13Still, Pharaoh’s heart was hardened, and he would not listen to them, just as the LORD had said.
