Ecclesiastes 7:19-22 - Wisdom Is Valuable, But No One Is Completely Righteous
19 Wisdom strengthens the wise more than ten mighty men who are in the city. 20 For there is not a just man upon earth, that does good, and sins not.
21 Also take not to heart all words that are spoken; lest you hear your servant curse you: 22 For oftentimes also your own heart knows that you yourself likewise have cursed others.
