15. What is crooked cannot be made straight,and what is lacking cannot be counted.
16. I said in my heart, “I have acquired great wisdom, surpassing all who were over Jerusalem before me, and my heart has 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 is but a striving after wind.
18. For in much wisdom is much vexation,and he who increases knowledge increases sorrow.
