3“Throw it on the ground,” said the LORD. So Moses threw it on the ground, and it became a snake, and he ran from it.
4“Stretch out your hand and grab it by the tail,” the LORD said to Moses, who reached out his hand and caught the snake, and it turned back into a staff in his hand.
5“This is so that they may believe that the LORD, the God of their fathers— the God of Abraham, the God of Isaac, and the God of Jacob — has appeared to you.”
— Exodus 4:3-5
