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?"
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."
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.
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.
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."
But Moses said, "No, LORD, don't send me. I have never been a good speaker, and I haven't become one since you began to speak to me. I am a poor speaker, slow and hesitant."
At this the LORD became angry with Moses and said, "What about your brother Aaron, the Levite? I know that he can speak well. In fact, he is now coming to meet you and will be glad to see you.
Then Moses went back to Jethro, his father-in-law, and said to him, "Please let me go back to my relatives in Egypt to see if they are still alive." Jethro agreed and told him good-bye.
Again the LORD said to Moses, "Now that you are going back to Egypt, be sure to perform before the king all the miracles which I have given you the power to do. But I will make the king stubborn, and he will not let the people go.
Then Zipporah, his wife, took a sharp stone, cut off the foreskin of her son, and touched Moses' feet with it. Because of the rite of circumcision she said to Moses, "You are a husband of blood to me." And so the LORD spared Moses' life.
Meanwhile the LORD had said to Aaron, "Go into the desert to meet Moses." So he went to meet him at the holy mountain; and when he met him, he kissed him.
Then Moses told Aaron everything that the LORD had said when he told him to return to Egypt; he also told him about the miracles which the LORD had ordered him to perform.
