Ecclesiastes 7:19-22 - Wisdom Is Valuable, But No One Is Completely Righteous
19 Wisdom given as strength to a wise person is better than having ten powerful men in the city. 20 For there is not a single righteous man on earth who practices good and does not sin.
21 Don't listen to everything that is spoken you may hear your servant cursing you, 22 since you also know how often you have cursed others.
