1. Yahweh said to Moses, “Behold, I have made you as God to Pharaoh; and Aaron your brother shall be your prophet.
2. You shall speak all that I command you; and Aaron your brother shall speak to Pharaoh, that he let the children of Israel go out of his land.
3. I will harden Pharaoh’s heart, and multiply my signs and my wonders in the land of Egypt.
4. But Pharaoh will not listen to you, and I will lay my hand on Egypt, and bring out my armies, my people the children of Israel, out of the land of Egypt by great judgments.
5. The Egyptians shall know that I am Yahweh, when I stretch out my hand on Egypt, and bring out the children of Israel from among them.”
6. Moses and Aaron did so. As Yahweh commanded them, so they did.
7. Moses was eighty years old, and Aaron eighty-three years old, when they spoke to Pharaoh.
8. Yahweh spoke to Moses and to Aaron, saying,
9. “When Pharaoh speaks to you, saying, ‘Perform a miracle!’ then you shall tell Aaron, ‘Take your rod, and cast it down before Pharaoh, that it become a serpent.’”
10. Moses and Aaron went in to Pharaoh, and they did so, as Yahweh had commanded: and Aaron cast down his rod before Pharaoh and before his servants, and it became a serpent.
