Ecclesiastes 1:15-17

King James Version

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

¹⁶ I communed with mine own heart, saying, Lo, I am come to great estate, and have gotten more wisdom than all they that have been before me in Jerusalem: yea, my heart had great experience of wisdom and knowledge.

¹⁷ And I gave my heart to know wisdom, and to know madness and folly: I perceived that this also is vexation of spirit.
