Exodus 7:10-12

¹⁰Moses and Aaron went in to Pharaoh, and they did so, as the LORD had commanded. Aaron cast down his rod before Pharaoh and before his servants, and it became a serpent.

¹¹Then Pharaoh also called for the wise men and the sorcerers. They also, the magicians of Egypt, did the same thing with their enchantments.

¹²For they each cast down their rods, and they became serpents; but Aaron’s rod swallowed up their rods.
