3. And I will render Pharaoh's heart obdurate, and multiply my signs and my wonders in the land of Egypt.
4. And Pharaoh will not hearken unto you; and I will lay my hand upon Egypt, and bring forth my hosts, my people, the children of Israel, out of the land of Egypt by great judgments.
5. And the Egyptians shall know that I am Jehovah, when I stretch forth my hand on Egypt, and bring out the children of Israel from among them.
6. And Moses and Aaron did as Jehovah had commanded them: so did they.
7. And Moses was eighty years old, and Aaron was eighty-three years old, when they spoke to Pharaoh.
8. And Jehovah spoke to Moses and to Aaron, saying,
9. When Pharaoh shall speak to you, saying, Do a miracle for yourselves, --then thou shalt say unto Aaron, Take thy staff and cast it before Pharaoh--it will become a serpent.
10. And Moses and Aaron went in to Pharaoh, and did so, as Jehovah had commanded; and Aaron cast down his staff before Pharaoh, and before his bondmen, and it became a serpent.
11. And Pharaoh also called the sages and the sorcerers; and they too, the scribes of Egypt, did so with their enchantments:
12. they cast down every man his staff, and they became serpents; but Aaron's staff swallowed up their staves.
13. And Pharaoh's heart was stubborn, and he hearkened not to them, as Jehovah had said.
