Exodus 4:13 WEB

¹¹  Yahweh said to him, 'Who made man's mouth? Or who makes one mute, or deaf, or seeing, or blind? Isn't it I, Yahweh?

¹²  Now therefore go, and I will be with your mouth, and teach you what you shall speak.'

¹³  He said, 'Oh, Lord, please send someone else.'

¹⁴  The anger of Yahweh was kindled against Moses, and he said, 'What about Aaron, your brother, the Levite? I know that he can speak well. Also, behold, he comes forth to meet you. When he sees you, he will be glad in his heart.

¹⁵  You shall speak to him, and put the words in his mouth. I will be with your mouth, and with his mouth, and will teach you what you shall do.
