Ecclesiastes 7:19-22

¹⁹ Wisdom strengtheneth the wise more than ten mighty men which are in the city. 

²⁰ For there is not a just man upon earth, that doeth good, and sinneth not.

²¹ Also take no heed unto all words that are spoken; lest thou hear thy servant curse thee:

²² For oftentimes also thine own heart knoweth that thou thyself likewise hast cursed others.
