Exodus 4:14-15

New Revised Standard Version Catholic Edition

¹⁴ Then the anger of the Lord was kindled against Moses and he said, “What of your brother Aaron the Levite? I know that he can speak fluently; even now he is coming out to meet you, and when he sees you his heart will be glad. ¹⁵ You shall speak to him and put the words in his mouth; and I will be with your mouth and with his mouth, and will teach you what you shall do.
