19Wisdom is a stronghold to the wise man more than ten rulers that are in a city.
20For there is not a righteous man upon earth, that doeth good, and sinneth not.
21Also take not heed unto all words that are spoken, lest thou hear thy servant curse thee;
22for oftentimes also thine own heart knoweth that thou thyself likewise hast cursed others.
23All this have I tried by wisdom; I said: 'I will get wisdom'; but it was far from me.
