Exodus 4:1-5

1But Moses protested again, “What if they won’t believe me or listen to me? What if they say, ‘The Lord never appeared to you’?”

2Then the Lord asked him, “What is that in your hand?” “A shepherd’s staff,” Moses replied.

3“Throw it down on the ground,” the Lord told him. So Moses threw down the staff, and it turned into a snake! Moses jumped back.

4Then the Lord told him, “Reach out and grab its tail.” So Moses reached out and grabbed it, and it turned back into a shepherd’s staff in his hand.

5“Perform this sign,” the Lord told him. “Then they will believe that the Lord, the God of their ancestors—the God of Abraham, the God of Isaac, and the God of Jacob—really has appeared to you.”
