Ecclesiastes 1:13-17

13And I set my heart to seek and search out by wisdom concerning all that is done under heaven; this burdensome task God has given to the sons of man, by which they may be exercised.

14I have seen all the works that are done under the sun; and indeed, all is vanity and grasping for the wind.

15What is crooked cannot be made straight, And what is lacking cannot be numbered.

16I communed with my heart, saying, “Look, I have attained greatness, and have gained more wisdom than all who were before me in Jerusalem. My heart has understood great wisdom and knowledge.”

17And I set my heart to know wisdom and to know madness and folly. I perceived that this also is grasping for the wind.
