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. (7:10)

Then Pharaoh also called the wise men and the sorcerers: now the magicians of Egypt, they also did in like manner with their enchantments. (7:11)

For they cast down every man his rod, and they became serpents: but Aaron's rod swallowed up their rods. (7:12)

And the magicians of Egypt did so with their enchantments: and Pharaoh's heart was hardened, neither did he hearken unto them; as the Lord had said. (7:22)

And the magicians did so with their enchantments, and brought up frogs upon the land of Egypt. (8:7)
