Exodus 4:10-16

Moses replied, “I have never been a good speaker. I wasn't one before you spoke to me, and I'm not one now. I am slow at speaking, and I can never think of what to say.” But the LORD answered, “Who makes people able to speak or makes them deaf or unable to speak? Who gives them sight or makes them blind? Don't you know that I am the one who does these things? Now go! When you speak, I will be with you and give you the words to say.” Moses begged, “LORD, please send someone else to do it.” The LORD became angry with Moses and said: What about your brother Aaron, the Levite? I know he is a good speaker. He is already on his way here to visit you, and he will be happy to see you again. Aaron will speak to the people for you, and you will be like me, telling Aaron what to say. I will be with both of you as you speak, and I will tell each of you what to do.
