Proverbs 18:19-21

New Revised Standard Version Catholic Edition

¹⁹ An ally offended is stronger than a city;^[a]
    such quarreling is like the bars of a castle.
²⁰ From the fruit of the mouth one’s stomach is satisfied;
    the yield of the lips brings satisfaction.
²¹ Death and life are in the power of the tongue,
    and those who love it will eat its fruits.
