Ecclesiastes 2:18-20

¹⁸I also began to hate all the hard work that I had done, because when I die, everything that I have acquired will belong to the next king.

¹⁹And ◄who/no one► knows RHQ whether he will be wise or whether he will be foolish. But even if he is foolish, he will acquire all the things that I worked very hard and wisely to get.

²⁰I thought about all the hard work that I had done. It seemed useless, and I became depressed/discouraged.
