Exodus 4:10-14

10Then Moses said to the Lord, ‘My Lord, I cannot speak well. I speak slowly and I speak with difficulty. I never could speak well. And even now, when you have spoken to me, I still cannot speak well.’

11Then the Lord said to Moses, ‘Who has made human mouths? Who makes a person that cannot speak? Who makes a person that cannot hear? Who makes a person who can see, or who cannot see? It is I, the Lord God!

12Now go! I will help you to speak well. I will teach you what you must say.’

13But Moses said, ‘My Lord, please send some other person. Do not send me!’

14Then the Lord became angry with Moses. He said, ‘Aaron, the Levite, is your brother. I know that he can speak very well. Look! He is coming to meet you now. When he sees you, he will be very happy.
