16 When I applied my heart to know wisdom, and to see ^ythe business that is done on earth, how neither ^zday nor night do one’s eyes see sleep, 17 then I saw all the work of God, that ^aman cannot find out the work that is done under the sun. However much man may toil in seeking, he will not find it out. Even though a wise man claims to know, ^bhe cannot find it out.
