Ecclesiastes 1:13; Ecclesiastes 1:16-18

Ecclesiastes 1:13

13 And I gave my heart to searching out in wisdom all things which are done under heaven: it is a hard thing which God has put on the sons of men to do.

Ecclesiastes 1:16-18

16 I said to my heart, See, I have become great and am increased in wisdom more than any who were before me in Jerusalem--yes, my heart has seen much wisdom and knowledge.

17 And I gave my heart to getting knowledge of wisdom, and of the ways of the foolish. And I saw that this again was desire for wind.

18 Because in much wisdom is much grief, and increase of knowledge is increase of sorrow.
