Exodus 4:8-17

Then the LORD said, “If the people do not believe you or pay attention to the first miracle, they may believe you when you show them this second miracle. After these two miracles, if they still do not believe or listen to you, take some water from the Nile River and pour it on the dry ground. The water will become blood when it touches the ground.” But Moses said to the LORD, “Please, Lord, I have never been a skilled speaker. Even now, after talking to you, I cannot speak well. I speak slowly and can’t find the best words.” Then the LORD said to him, “Who made a person’s mouth? And who makes someone deaf or not able to speak? Or who gives a person sight or blindness? It is I, the LORD. Now go! I will help you speak, and I will teach you what to say.” But Moses said, “Please, Lord, send someone else.” The LORD became angry with Moses and 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. You will speak to Aaron and tell him what to say. I will help both of you to speak and will teach you what to do. 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, and use it to do the miracles.”
