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. ¹³ And Pharaoh's heart became hard, that he hearkened not unto them as the LORD had said.
