7 Moses was 80 years old and Aaron 83 when they spoke to Pharaoh.
8 The Lord said to Moses and Aaron,
9 “When Pharaoh tells you, ‘Perform a miracle,’ tell Aaron, ‘Take your staff and throw it down before Pharaoh. It will become a serpent.’ ”
10 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.
11 But then Pharaoh called the wise men and sorcerers — the magicians of Egypt, and they also did the same thing by their occult practices.
12 Each one threw down his staff, and it became a serpent. But Aaron’s staff swallowed their staffs.
13 However, Pharaoh’s heart hardened, and he did not listen to them, as the Lord had said.
