Ecclesiastes 2:18; Ecclesiastes 2:21; Ecclesiastes 2:26

18 I hated all the things I had toiled for under the sun, because I must leave them to the one who comes after me.

21 For a person may labor with wisdom, knowledge and skill, and then they must leave all they own to another who has not toiled for it. This too is meaningless and a great misfortune.

26 To the person who pleases him, God gives wisdom, knowledge and happiness, but to the sinner he gives the task of gathering and storing up wealth to hand it over to the one who pleases God. This too is meaningless, a chasing after the wind.
