Exodus 4
10 Ref Moses said to Yahweh, "Oh, Lord, I am not eloquent, neither before now, nor since you have spoken to your servant; for I am slow of speech, and of a slow tongue."
11 Ref Yahweh said to him, "Who made man's mouth? Or who makes one mute, or deaf, or seeing, or blind? Isn't it I, Yahweh?
12 Ref Now therefore go, and I will be with your mouth, and teach you what you shall speak."
13 Ref He said, "Oh, Lord, please send someone else."
14 Ref The anger of Yahweh was kindled against Moses, and he said, "What about Aaron, your brother, the Levite? I know that he can speak well. Also, behold, he comes forth to meet you. When he sees you, he will be glad in his heart.
15 Ref You shall speak to him, and put the words in his mouth. I will be with your mouth, and with his mouth, and will teach you what you shall do.
16 Ref He will be your spokesman to the people; and it will happen, that he will be to you a mouth, and you will be to him as God.
