Ecclesiastes 7:19-22 - Wisdom Is Valuable, But No One Is Completely Righteous
19 Wisdom gives more strength to the wise than ten rulers who are in the city. 20 Surely there is no one righteous on the earth who [continually] does good and never sins.
21 Do not pay attention to everything people say, lest you hear your own servant curse you. 22 For your heart knows that you also have cursed others many times.
