Exodus 7:9-11

21st Century King James Version

⁹ “When Pharaoh shall speak unto you, saying, ‘Show a miracle for yourselves,’ then thou shalt say unto Aaron, ‘Take thy rod and cast it before Pharaoh, and it shall become a serpent.’”

¹⁰ And Moses and Aaron went in unto 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.
