Exodus 4:1-5

1Then Moses replied, ‘Perhaps the leaders of Israel will not believe me. Perhaps they will not listen to my message. Perhaps they will say, “The Lord did not really appear to you.” ’

2Then the Lord said to Moses, ‘What is that thing in your hand?’ Moses answered, ‘It is a stick.’

3The Lord said, ‘Throw it down on the ground.’ So Moses threw it on the ground. Then the stick became a snake! Moses ran away from the snake.

4Then the Lord said to Moses, ‘Take hold of the snake's tail with your hand.’ So Moses caught the snake with his hand. Then it became a stick in his hand again.

5God said, ‘Do this in front of them. Then they will believe you. They will believe that I, the Lord God, have appeared to you. I am the God that their ancestors worshipped. I am the God of Abraham, the God of Isaac and the God of Jacob.’
