Exodus 4:10-13 And Moses said to Jehovah, Oh, Lord, I am not a man of words, neither yesterday nor in any time past, nor since you have spoken to your servant, because I am slow of speech and of a slow tongue.

MLV⁽ⁱ⁾ ¹⁰ And Moses said to Jehovah, Oh, Lord, I am not a man of words, neither yesterday nor in any time past, nor since you have spoken to your servant, because I am slow of speech and of a slow tongue. ¹¹ And Jehovah said to him, Who has made man's mouth? Or who makes a man dumb, or deaf, or seeing, or blind? Is it not I, Jehovah? ¹² Now therefore go and I will be with your mouth and teach you what you will speak.
¹³ And he said, Oh, Lord, I beseech you, send by the hand of him whom you will send.
