Exodus 4:10-13

4:10 Then Moses said to the Lord, “O my Lord, I am not an eloquent man, neither in the past nor since you have spoken to your servant, for I am slow of speech and slow of tongue.”

4:11 The Lord said to him, “Who gave a mouth to man, or who makes a person mute or deaf or seeing or blind? Is it not I, the Lord? 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!”
