Ecclesiastes 4:4; Ecclesiastes 4:6; Ecclesiastes 4:16

4 And I saw that all toil and all achievement spring from one person’s envy of another. This too is meaningless, a chasing after the wind.
6 Better one handful with tranquillity than two handfuls with toil and chasing after the wind.
16 There was no end to all the people who were before them. But those who came later were not pleased with the successor. This too is meaningless, a chasing after the wind.
