Exodus 4:4-6

Common English Bible

⁴ Then the Lord said to Moses, “Reach out and grab the snake by the tail.” So Moses reached out and grabbed it, and it turned back into a rod in his hand. ⁵ “Do this so that they will believe that the Lord, the God of their ancestors, Abraham’s God, Isaac’s God, and Jacob’s God has in fact appeared to you.”

⁶ Again, the Lord said to Moses, “Put your hand inside your coat.” So Moses put his hand inside his coat. When he took his hand out, his hand had a skin disease flaky like snow.
