Exodus 4:11-16

11And the LORD said to him, Who hath made man’s mouth? or who maketh the dumb, or deaf, or the seeing, or the blind? have not I the LORD? 12Now therefore go, and I will be with thy mouth, and teach thee what thou shalt say. 13And he said, O my Lord, send, I pray thee, by the hand of him whom thou wilt send.1 14And the anger of the LORD was kindled against Moses, and he said, Is not Aaron the Levite thy brother? 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 to him, and put 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 speak for thee to the people: and he shall be, even he shall be to thee instead of a mouth, and thou shalt be to him instead of God.
