Ecclesiastes 8
15 Ref Then I commended mirth, because a man has no better thing under the sun, than to eat, and to drink, and to be joyful: for that will accompany him in his labor all the days of his life which God has given him under the sun.
16 Ref When I applied my heart to know wisdom, and to see the business that is done on the earth (for also there is that neither day nor night sees sleep with his eyes),
17 Ref then I saw all the work of God, that man can't find out the work that is done under the sun, because however much a man labors to seek it out, yet he won't find it. Yes even though a wise man thinks he can comprehend it, he won't be able to find it.
