6 And Moses and Aaron did as the Lord commanded them, so did they.
7 And Moses was eighty years old and Aaron eighty-three years old when they spoke unto Pharaoh.
8 And the Lord spoke unto Moses and unto Aaron, saying,
9 If Pharaoh shall answer you, saying, Show a miracle, then thou shalt say unto Aaron, Take thy rod and cast it before Pharaoh, that it shall become a dragon.
10 So Moses and Aaron went in unto Pharaoh, and they did as the Lord had commanded; and Aaron cast down his rod before Pharaoh and before his slaves, and it became a dragon.
11 Then Pharaoh also called wise men and sorcerers; now the magicians of Egypt, they also did in like manner with their fire worship.
12 For each one cast down his rod, and they became dragons; but Aaron’s rod swallowed up their rods.
