Exodus 4:1-9

1 Then Moses answered the Lord, "But suppose the Israelites do not believe me and will not listen to what I say. What shall I do if they say that you did not appear to me?"
2 So the Lord asked him, "What are you holding?" "A walking stick," he answered.
3 The Lord said, "Throw it on the ground." When Moses threw it down, it turned into a snake, and he ran away from it.
4 Then the Lord said to Moses, "Reach down and pick it up by the tail." So Moses reached down and caught it, and it became a walking stick again.
5 The Lord said, "Do this to prove to the Israelites that the Lord, the God of their ancestors, the God of Abraham, Isaac, and Jacob, has appeared to you."
6 The Lord spoke to Moses again, "Put your hand inside your robe." Moses obeyed; and when he took his hand out, it was diseased, covered with white spots, like snow.
7 Then the Lord said, "Put your hand inside your robe again." He did so, and when he took it out this time, it was healthy, just like the rest of his body.
8 The Lord said, "If they will not believe you or be convinced by the first miracle, then this one will convince them.
9 If in spite of these two miracles they still will not believe you, and if they refuse to listen to what you say, take some water from the Nile and pour it on the ground. The water will turn into blood."
