Exodus 4:11-16

11And Jehovah said unto him, Who hath made man’s mouth? or who maketh a man dumb, or deaf, or seeing, or blind? is it not I, Jehovah? 12Now therefore go, and I will be with thy mouth, and teach thee what thou shalt speak. 13And he said, Oh, Lord, send, I pray thee, by the hand of him whom thou wilt send. 14And the anger of Jehovah was kindled against Moses, and he said, Is there not Aaron thy brother the Levite? I know that he can speak well. And also, behold, he cometh forth to meet thee: and when he seeth thee, he will be glad in his heart. 15And thou shalt speak unto him, and put the words in his mouth: and I will be with thy mouth, and with his mouth, and will teach you what ye shall do. 16And he shall be thy spokesman unto the people; and it shall come to pass, that he shall be to thee a mouth, and thou shalt be to him as God.
