1. So the Lord said to Moses, “See, I have made you a god to Pharaoh, and Aaron your brother will be your prophet.
2. You shall speak all that I command you, and Aaron your brother shall tell Pharaoh to send the children of Israel out of his land.
3. But I will harden Pharaoh’s heart and multiply My signs and My wonders in the land of Egypt.
4. Nevertheless, Pharaoh will not listen to you, so that I may lay My hand upon Egypt and bring forth My armies and My people, the children of Israel, out of the land of Egypt by great judgments.
5. And the Egyptians shall know that I am the Lord when I stretch forth My hand upon Egypt and bring out the children of Israel from among them.”
6. So Moses and Aaron did it. Just as the Lord commanded them, so they did.
7. Moses was eighty years old, and Aaron was eighty-three years old when they spoke to Pharaoh.
8. Now the Lord spoke to Moses and to Aaron, saying,
9. “When Pharaoh shall speak to you, saying, ‘Show a miracle,’ then you shall say to Aaron, ‘Take your rod, and throw it before Pharaoh,’ and it shall become a serpent.”
10. So Moses and Aaron went to Pharaoh, and they did what the Lord had commanded. And Aaron threw down his rod before Pharaoh and before his servants, and it became a serpent.
11. Then Pharaoh also called the wise men and the sorcerers. Then the magicians of Egypt likewise performed with their secret arts.
12. For every man threw down his rod, and they became serpents. But Aaron’s rod swallowed up their rods.
13. Nonetheless, Pharaoh’s heart hardened so that he would not listen to them, just as the Lord had said.
