Aaron threw his staff down …
and it became a snake …
the Egyptian magicians also did the same things …
but Aaron’s rod swallowed up their staffs.

Exodus 7:10-11

At the front of Pharaoh’s crown was an enraged cobra, symbol of his sovereignty and power. Through this sign of the snake, God both challenged Pharaoh’s sovereignty and power, and also foretold Pharaoh’s ultimate defeat. Aaron’s snake swallowed Pharaoh’s snakes.
Ultimately, the waters of the Red Sea would swallow Pharaoh’s army.
Game over.
