Exodus 4:1-7

Then Moses answered, “What if the people of Israel do not believe me or listen to me? What if they say, ‘The LORD did not appear to you’?” The LORD said to him, “What is that in your hand?” Moses answered, “It is my walking stick.” The LORD said, “Throw it on the ground.” So Moses threw it on the ground, and it became a snake. Moses ran from the snake, but the LORD said to him, “Reach out and grab the snake by its tail.” When Moses reached out and took hold of the snake, it again became a stick in his hand. The LORD said, “This is so that the Israelites will believe that the LORD appeared to you. I am the God of their ancestors, the God of Abraham, the God of Isaac, and the God of Jacob.” Then the LORD said to Moses, “Put your hand inside your coat.” So Moses put his hand inside his coat. When he took it out, it was white with a skin disease. Then he said, “Now put your hand inside your coat again.” So Moses put his hand inside his coat again. When he took it out, his hand was healthy again, like the rest of his skin.
