Exodus 4:1-5

1Moses answered, “What if they won’t believe me and will not obey me but say, ‘The Lord did not appear to you’?”

2The Lord asked him, “What is that in your hand?” “A staff,” he replied.

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

4The Lord told Moses, “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 that they will believe that the Lord, the God of their ancestors, the God of Abraham, the God of Isaac, and the God of Jacob, has appeared to you.”
