Moses spoke to the Lord. He said, "Lord, I've never been a good speaker. And I haven't gotten any better since you spoke to me. I don't speak very well at all." The LORD said to him, "Who makes a man able to talk? Who makes him unable to hear or speak? Who makes him able to see? Who makes him blind? It is I, the Lord. Now go. I will help you speak. I will teach you what to say."
- Exodus 4:10-12
