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 have gotten me great wisdom above all that were before me in Jerusalem: yea, my heart hath had great experience of wisdom and knowledge.
17. And I applied my heart to know wisdom, and to know madness and folly: I perceived that this also was a striving after wind.
18. For in much wisdom is much grief: and he that increaseth knowledge increaseth sorrow.
