Ecclesiastes 7:19-21

New Catholic Bible

¹⁹ Wisdom gives greater strength to the wise man
    than ten rulers in a city.
²⁰ There is no one on earth who is so righteous
    that he does nothing but good and never sins.^[a]
21 If you do not pay attention to all that people say,
    you will never hear your servant speaking ill of you.
