Proverbs 18:19-21

Revised Standard Version

¹⁹ A brother helped is like a strong city,^[a]
    but quarreling is like the bars of a castle.
²⁰ From the fruit of his mouth a man is satisfied;
    he is satisfied by the yield of his lips.
²¹ Death and life are in the power of the tongue,
    and those who love it will eat its fruits.
