14 Here also is a futility that goes on upon the earth: there are righteous men who fare as though they were wicked, and wicked men who fare as though they were righteous. I say that this also is vanity (emptiness, falsity, and futility)! 15 Then I commended enjoyment, because a man has no better thing under the sun [without God] than to eat and to drink and to be joyful, for that will remain with him in his toil through the days of his life which God gives him under the sun.
16 When I applied my mind to know wisdom and to see the business activity and the painful effort that take place upon the earth--how neither day nor night some men's eyes sleep-- 17 Then I saw all the work of God, that man cannot find out the work that is done under the sun--because however much a man may toil in seeking, yet he will not find it out; yes, more than that, though a wise man thinks and claims he knows, yet will he not be able to find it out.
