Proverbs 14:28-30

New Revised Standard Version, Anglicised

²⁸ The glory of a king is a multitude of people;
    without people a prince is ruined.
²⁹ Whoever is slow to anger has great understanding,
    but one who has a hasty temper exalts folly.
³⁰ A tranquil mind gives life to the flesh,
    but passion makes the bones rot.
