Ecclesiastes 7:19-22 - Wisdom Is Valuable, But No One Is Completely Righteous
19 Wisdom gives a wise person more protection than ten rulers in a city. 20 For there is not one truly righteous person on the earth who continually does good and never sins.
21 Also, do not pay attention to everything that people say; otherwise, you might even hear your servant cursing you. 22 For you know in your own heart that you also have cursed others many times.
