Proverbs 9:6
Do not rebuke: Do not rebuke mockers or they will hate you; rebuke the wise and they will love you. The wise person, by contrast, receives rebuke gratefully. To 'rebuke the wise' (yakiach chacham) results in love and gratitude. This contrast reveals the character difference: the fool hates those who correct him, while the wise person loves those who help him toward greater understanding. The wise person understands that correction is care. The fool sees it as attack.
