Ecclesiastes 7:19-22

Wisdom strengthens the wise man more than ten rulers who are in a city. [Ps 127:1; 2 Tim 3:15] Indeed, there is not a righteous man on earth who always does good and who never sins. [Is 53:6; Rom 3:23] Also, do not take seriously everything that is said, so that you will not hear your servant cursing you, for you also know that you too have cursed others many times.
