ERV(i)
15 Then I commended mirth, because a man hath no better thing under the sun, than to eat, and to drink, and to be merry: for that shall abide with him in his labour [all] the days of his life which God hath given him under the sun.
16 When I applied mine heart to know wisdom, and to see the business that is done upon the earth: (for also there is that neither day nor night seeth sleep with his eyes:)
17 then I beheld all the work of God, that man cannot find out the work that is done under the sun: because however much a man labour to seek it out, yet he shall not find it; yea moreover, though a wise man think to know it, yet shall he not be able to find it.
