6And Moses and Aaron did as the LORD commanded them, so they did.
7And Moses was eighty years old, and Aaron eighty-three years old, when they spoke to Pharaoh.
8And the LORD spoke to Moses and to Aaron, saying,
9When Pharaoh shall speak to you, saying, Show a miracle for you, then you shall say to Aaron, Take your rod, and cast it before Pharaoh, and it shall become a serpent.
10And Moses and Aaron went 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.
11Then Pharaoh also called the wise men and the sorcerers, now the magicians of Egypt, they also did in like manner with their enchantments.
12For they cast down every man his rod, and they became serpents, but Aaron's rod swallowed up their rods.
13And he hardened Pharaoh's heart, that he did not listen to them, as the LORD had said.
