Ecclesiastes 1:16-18 - The Spokesman Begins To Study Life
16 I spoke within my own heart, saying, Lo, I have become great and have gathered more wisdom than all that have been before me in Jerusalem; yea, my heart has seen much of wisdom and knowledge. 17 And I gave my heart to know wisdom and to know madness and folly; I know that this also is vexation of spirit.
18 For in much wisdom is much grief; and he who increases knowledge increases sorrow.
