Ecclesiastes 2:22

Painful Days and Restless Nights

2:22 What does a man acquire from all his labor

and from the anxiety that accompanies his toil on earth?

Ecclesiastes 1:17

1:17 So I decided to discern the benefit of wisdom and knowledge over foolish behavior and ideas;

however, I concluded that even this endeavor is like trying to chase the wind!

Ecclesiastes 4:16

4:16 There is no end to all the people nor to the past generations,

yet future generations will not rejoice in him.

This also is profitless and like chasing the wind.
