Thematic Bible: Moses was slow of speech

Then Moses said unto the LORD, O my Lord, I am not eloquent, neither up until now, nor since thou hast spoken unto thy slave; but I am slow of speech and of a slow tongue. And the LORD said unto him, Who has made man's mouth? Or who makes the dumb or the deaf or the seeing or the blind? Am not I the LORD? Now therefore go and I will be with thy mouth and teach thee what thou shalt say.
