5. The Egyptians will know that I am Yahweh when I stretch out My hand against Egypt, and bring out the Israelites from among them.”
6. So Moses and Aaron did this; they did just as the Lord commanded them.
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.
