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.”
10. 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.”
11. The Lord said to him, “Who gives man his mouth? Who makes him deaf or dumb? Who gives him sight or makes him blind? It is I, the Lord.
12. Now, go! I will help you to speak, and I will tell you what to say.”
13. But Moses answered, “No, Lord, please send someone else.”
14. 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.
