Ecclesiastes 1:16-18

Darby Translation

¹⁶ I communed with mine own heart, saying, Lo, I have become great and have acquired wisdom more than all they that have been before me over Jerusalem; and my heart hath seen much of wisdom and knowledge.

¹⁷ And I applied my heart to the knowledge of wisdom, and to the knowledge of madness and folly: I perceived that this also is a striving after the wind.

¹⁸ For in much wisdom is much vexation, and he that increaseth knowledge increaseth sorrow.
