Ecclesiastes 2:17-20

17So I hated life. Everything that happens on the earth only brings me trouble. Nothing has any purpose. It is as useless as somebody who tries to catch the wind.

18I thought about all the hard work that I have done here on the earth. When I die, all the things that I worked so hard to get will belong to the next king. So I hated all my hard work.

19The next king may be a wise man, or he may be a foolish man. Nobody knows! But all the things that I used my wisdom and hard work to get will belong to him. All this has no purpose.

20So I was very upset when I thought about all my hard work on the earth.
