Exodus 4:1-5

1Moses answered again, “And if they do not believe me or pay attention to me, but say, ‘The Lord has not appeared to you’?”

2The Lord said to him, “What is that in your hand?” He said, “A staff.”

3The Lord said, “Throw it to the ground.” So he threw it to the ground, and it became a snake, and Moses ran from it.

4But the Lord said to Moses, “Put out your hand and grab it by the tail” – so he put out his hand and caught it, and it became a staff in his hand –

5“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.”
