Exodus 4:13-15

King James Version

¹³ And he said, O my Lord, send, I pray thee, by the hand of him whom thou wilt send.

¹⁴ And 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.

¹⁵ And thou shalt speak unto 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.
