Proverbs 14:28-30

New Catholic Bible

²⁸ Many subjects ensure the glory of a king,
    but if his subjects are few, he is of no importance.
²⁹ A patient man shows good sense,
    but a quick-tempered man displays the height of folly.
³⁰ A tranquil heart gives life to the body,
    but envy causes the bones to rot.
