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.
