Multiple commentators (Barnes, Ellicott, Gill) highlight that Job's sharp remark directly echoes Proverbs 17:28: 'Even a fool, when he holdeth his peace, is counted wise.' Job is telling his friends that since their words are neither comforting nor accurate, the wisest thing they could do is stop talking. This serves as a timeless lesson on the value of thoughtful silence over unhelpful speech, especially when ministering to the suffering.
