Ecclesiastes 7:16-25

16Be not righteous overmuch; neither make thyself overwise: why shouldest thou destroy thyself? 17Be not overmuch 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 thy hand: for he that feareth God shall come forth from them all.

19Wisdom is a strength to the wise man more than ten rulers that 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.

23All this have I proved in wisdom: I said, I will be wise; but it was far from me. 24That which is, is far off and exceeding deep; who can find it out? 25I turned about, and my heart was set to know and to search out, and to seek wisdom and the reason of things, and to know that wickedness is folly, and that foolishness is madness.
