Ecclesiastes 1:13-17

¹³And I applied my heart to seek and search out by wisdom concerning all that is done under the heavens: this grievous occupation hath God given to the children of men to weary themselves therewith.

¹⁴I have seen all the works that are done under the sun, and behold, all is vanity and pursuit of the wind.

¹⁵That which is crooked cannot be made straight; and that which is wanting cannot be numbered.

¹⁶I communed with mine own heart, saying, Lo, I have become great and have acquired wisdom more than all they that have been before me over Jerusalem; and my heart hath seen much of wisdom and knowledge.

¹⁷And I applied my heart to the knowledge of wisdom, and to the knowledge of madness and folly: I perceived that this also is a striving after the wind.
