Exodus 7:10-12

¹⁰Moses and Aaron went to Pharaoh and did what the Lord had ordered. Aaron threw down his staff in front of Pharaoh and his officials, and it turned into a snake.

¹¹But Pharaoh called in wise men and sorcerers, and these Egyptian magicians did the same thing using their magic arts.

¹²Each of them threw down their walking sticks and they also turned into snakes, but Aaron's walking stick swallowed up all their walking sticks.
