3. And I will harden Pharaoh’s heart, and multiply My signs and My wonders in the land of Egypt.
4. But Pharaoh will not heed you, so that I may lay My hand on Egypt and bring 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 out My hand on Egypt and bring out the children of Israel from among them.”
6. Then Moses and Aaron did so; just as the Lord commanded them, so they did.
7. And Moses was eighty years old and Aaron eighty-three years old when they spoke to Pharaoh.
8. Then the Lord spoke to Moses and Aaron, saying,
9. “When Pharaoh speaks to you, saying, ‘Show a miracle for yourselves,’ then you shall say to Aaron, ‘Take your rod and cast it before Pharaoh, and let it become a serpent.’ ”
10. So Moses and Aaron went in to Pharaoh, and they did so, just as the Lord commanded. And Aaron cast down his rod before Pharaoh and before his servants, and it became a serpent.
11. But Pharaoh also called the wise men and the sorcerers; so the magicians of Egypt, they also did in like manner with their enchantments.
