Ecclesiastes 7:19-22 - Wisdom Is Valuable, But No One Is Completely Righteous
19 Wisdom makes the wise stronger than ten mighty ones who are in the city. 20 For there is not a just man on earth who does good and does not sin.
21 Also do not listen to all words that are spoken; lest you hear your servant curse you. 22 For also your own heart knows that you yourself have also cursed others many times.
