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 2:19

2:19 Who knows if he will be a wise man or a fool?

Yet he will be master over all the fruit of my labor

for which I worked so wisely on earth!

This also is futile!

Ecclesiastes 3:19

3:19 For the fate of humans and the fate of animals are the same:

As one dies, so dies the other; both have the same breath.

There is no advantage for humans over animals,

for both are fleeting.
