Ecclesiastes 7:18-22

It is good that you grasp one thing while not letting go of the other; for one who fears God comes out with both of them.

Wisdom strengthens a wise person more than ten rulers who are in a city.

Indeed, there is not a righteous person on earth who always does good and does not ever sin.

Also, do not take seriously all the words which are spoken, so that you do not hear your servant cursing you,

for you know that even you have cursed others many times as well.
