Exodus 4:2-5
3 Then He said, “Throw it on the ground.” He threw it on the ground, and it became a snake. Moses ran from it,
4 but the Lord told him, “Stretch out your hand and grab it by the tail.” So he stretched out his hand and caught it, and it became a staff in his hand.
5 “This will take place,” He continued, “so they will believe that Yahweh, the God of their fathers, the God of Abraham, the God of Isaac, and the God of Jacob, has appeared to you.”(A)
