Proverbs 17:20-22

Revised Standard Version Catholic Edition

²⁰ A man of crooked mind does not prosper,
    and one with a perverse tongue falls into calamity.
²¹ A stupid son is a grief to a father;
    and the father of a fool has no joy.
²² A cheerful heart is a good medicine,
    but a downcast spirit dries up the bones.
