Ecclesiastes 1:16-18 - The Spokesman Begins To Study Life
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.
