John Cassian, on Prov 29:20

“Hast thou seen a man hasty to speak? folly is rather to be looked for, than his amendment.”

“In all things be "quick to listen and slow to speak" lest the remark of Solomon be fulfilled in you: "If you see a man too ready of speech, know that a fool has more hope than he." And never dare to teach someone what you have not practiced yourself.”
