Exodus 7:10-12

¹⁰So Moses and Aaron went in unto Pharao, and did as the Lord had commanded. And Aaron took the rod before Pharao, and his servants, and it was turned into a serpent.

¹¹And Pharao called the wise men and the magicians: and they also by Egyptian enchantments and certain secrets did in like manner.

¹²And they every one cast down their rods, and they were turned into serpents: but Aaron’s rod devoured their rods.
