Ecclesiastes 1:13; Ecclesiastes 1:16-18

Ecclesiastes 1:13

13 And I applied my heart to seek and to search out by wisdom all that is done under heaven. It is an unhappy business that God has given to the children of man to be busy with.

Ecclesiastes 1:16-18

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.
