7. And Moses was eighty years old, and Aaron eighty and three years old, when they spoke to Pharaoh.
8. And the LORD spoke to Moses, and to Aaron, saying,
9. When Pharaoh shall speak to you, saying, Show a miracle for you: then thou shalt say to Aaron, Take thy rod, and cast it before Pharaoh, and it shall become a serpent.
10. And Moses and Aaron went in to Pharaoh, and they did so as the LORD had commanded: And Aaron cast down his rod before Pharaoh, and before his servants, and it became a serpent.
