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.
