Exodus 4:12-14 American Standard Version (ASV)
12 Now therefore go, and I will be with thy mouth, and teach thee what thou shalt speak. 13 And he said, Oh, Lord, send, I pray thee, by the hand of him whom thou wilt send. 14 And 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.
