Exodus 4:12-14

4:12 So now go, and I will be with your mouth and will teach you what you must say.”

4:13 But Moses said, “O my Lord, please send anyone else whom you wish to send!”

4:14 Then the Lord became angry with Moses, and he said, “What about your brother Aaron the Levite? I know that he can speak very well. Moreover, he is coming to meet you, and when he sees you he will be glad in his heart.
