Exodus 7:10-12

¹⁰And Moses and Aaron went in before Pharao, and before his servants, and they did so, as the Lord commanded them; and Aaron cast down his rod before Pharao, and before his servants, and it became a serpent.

¹¹But Pharao called together the wise men of Egypt, and the sorcerers, and the charmers also of the Egyptians did likewise with their sorceries.

¹²And they cast down each his rod, and they became serpents, but the rod of Aaron swallowed up their rods.
