Exodus 4:14-16

Darby Translation

¹⁴ Then the anger of Jehovah 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 goeth out to meet thee; and when he seeth thee he will be glad in his heart.

¹⁵ And 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.

¹⁶ And he shall speak for thee unto the people; and it shall come to pass that he shall be to thee for a mouth, and thou shalt be to him for God.
