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 7:25

True Righteousness and Wisdom are Virtually Nonexistent

7:25 I tried to understand, examine, and comprehend

the role of wisdom in the scheme of things,

and to understand the stupidity of wickedness and the insanity of folly.

Ecclesiastes 8:16-17

Limitations of Human Wisdom

8:16 When I tried to gain wisdom

and to observe the activity on earth –

even though it prevents anyone from sleeping day or night –

8:17 then I discerned all that God has done:

No one really comprehends what happens on earth.

Despite all human efforts to discover it, no one can ever grasp it.

Even if a wise person claimed that he understood,

he would not really comprehend it.
