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