Exodus 4:10-17

But Moses said to the Lord, “But Lord, I am not a skilled speaker. I have never been able to speak well. And now, even after talking to you, I am not a good speaker. I speak slowly and can’t find the best words.” Then the Lord said to him, “Who made man’s mouth? And who makes him deaf or not able to speak? Or who gives a man sight or makes him blind? It is I, the Lord. Now go! I will help you speak. I will tell you what to say.” But Moses said, “Please, Lord, send someone else.” The Lord became angry with Moses. He said, “Your brother Aaron, from the family of Levi, is a skilled speaker. He is already coming to meet you. And he will be happy when he sees you. I will tell you what to say. Then you will tell Aaron. I will help both of you know what to say and do. And Aaron will speak to the people for you. You will tell him what God says. And he will speak for you. Take your walking stick with you. Use it to do the miracles.”
