Ecclesiastes 7:15-22

15All this have I seen in the days of my vanity: there is a righteous man that perisheth in his righteousness, and there is a wicked man that prolongeth his life in his evil-doing.

16Be not righteous over much; neither make thyself over wise: why shouldest thou destroy thyself?

17Be not over much wicked, neither be thou foolish: why shouldest thou die before thy time?

18It is good that thou shouldest take hold of this; yea, also from that withdraw not thine hand: for he that feareth God shall come forth of them all.

19Wisdom is a strength to the wise man more than ten rulers which are in a city.

20Surely 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.
