Proverbs 13:2-4

New Catholic Bible

² A good man derives nourishment from the fruit of his words,
    but one who is treacherous craves violence.
³ He who guards his mouth makes his life secure,
    but one who talks excessively ensures his own downfall.^[a]
4 The idler^[b] craves for food and remains unsatisfied,
    but the appetite of the diligent is fully sated.
