Exodus 4:1-3

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.
