Proverbs 14:29-31

Revised Standard Version

²⁹ He who is slow to anger has great understanding,
    but he who has a hasty temper exalts folly.
³⁰ A tranquil mind gives life to the flesh,
    but passion makes the bones rot.
³¹ He who oppresses a poor man insults his Maker,
    but he who is kind to the needy honors him.
