1. The Lord answered Moses, “See, I have made you like God to Pharaoh, and Aaron your brother will be your prophet.
2. You must say whatever I command you; then Aaron your brother must declare it to Pharaoh so that he will let the Israelites go from his land.
3. But I will harden Pharaoh’s heart and multiply My signs and wonders in the land of Egypt.
4. Pharaoh will not listen to you, but I will put My hand on Egypt and bring the divisions of My people the Israelites out of the land of Egypt by great acts of judgment.
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.
