17
I applied my mind to know wisdom and knowledge, madness and folly; I learned that this too is a pursuit of the wind.
Ecclesiastes 1:17 In-Context
15
What is crooked cannot be straightened; what is lacking cannot be counted.
16
I said to myself, “Look, I have increased in wisdom more than anyone who has ruled over Jerusalem before me; I have experienced much of wisdom and knowledge.”
17
Then I applied myself to the understanding of wisdom, and also of madness and folly, but I learned that this, too, is a chasing after the wind.
18
For with much wisdom comes much sorrow; the more knowledge, the more grief.
