Exodus 4:10-12

10Moses said to the Lord, “Please, Lord, I’m not a good speaker. I’ve never been a good speaker, and I’m not now, even though you’ve spoken to me. I speak slowly, and I become tongue-tied easily.”

11The Lord asked him, “Who gave humans their mouths? Who makes humans unable to talk or hear? Who gives them sight or makes them blind? It is I, the Lord!

12Now go, and I will help you speak and will teach you what to say.”
