Exodus 7:10-12

¹⁰Then Moses and Aaron went to Pharaoh, and they did just as Yahweh had commanded. Aaron threw down his staff before Pharaoh and his servants, and it became a snake.

¹¹Then Pharaoh also called for his wise men and sorcerers. They did the same thing by their magic.

¹²Each man threw down his staff, and the staffs became snakes. But Aaron's staff swallowed up their snakes.
