Exodus 4:10-11
Exodus 4:10-11 ASV
And Moses said unto Jehovah, Oh, Lord, I am not eloquent, neither heretofore, nor since thou hast spoken unto thy servant; for I am slow of speech, and of a slow tongue. And Jehovah said unto him, Who hath made man’s mouth? or who maketh a man dumb, or deaf, or seeing, or blind? is it not I, Jehovah?
