Exodus 4, 14 – 17 „Then the LORD became angry with Moses and said: I know there is your brother, Aaron the Levite, who is a good speaker; even now he is on his way to meet you. When he sees you, he will truly be glad. 15You will speak to him and put the words in his mouth. I will assist both you and him in speaking and teach you both what you are to do. 16He will speak to the people for you: he will be your spokesman, and you will be as God to him. 17Take this staff in your hand; with it you are to perform the signs”.
