Charles Ellicott Commentary Proverbs 29:20

"Seest thou a man that is hasty in his words? There is more hope of a fool than of him." — Proverbs 29:20 (ASV)

There is more hope of a fool (khesîl) than of him. —The fool is a dull, self-satisfied person, but may learn better; the man who is hasty and ill-advised in his words has a harder task before him in governing his tongue. (Compare to James 3:2 and following)
