Proverbs 17:5-7

Revised Standard Version Catholic Edition

⁵ He who mocks the poor insults his Maker;
    he who is glad at calamity will not go unpunished.
⁶ Grandchildren are the crown of the aged,
    and the glory of sons is their fathers.
⁷ Fine speech is not becoming to a fool;
    still less is false speech to a prince.
