10But Moses said to the Lord, “Oh, my Lord, I am not eloquent, either in the past or since you have spoken to your servant, but dI am slow of speech and of tongue.” 11Then the Lord said to him, “Who has made man’s mouth? Who makes him mute, or deaf, or seeing, or blind? Is it not I, the Lord? 12Now therefore go, and eI will be with your mouth and teach you what you shall speak.”
