Proverbs 17:20-22

New Revised Standard Version, Anglicised

²⁰ The crooked of mind do not prosper,
    and the perverse of tongue fall into calamity.
²¹ The one who begets a fool gets trouble;
    the parent of a fool has no joy.
²² A cheerful heart is a good medicine,
    but a downcast spirit dries up the bones.
