Ecclesiastes 1:2-3; Ecclesiastes 1:14; Ecclesiastes 1:17

2 All is to no purpose, said the Preacher, all the ways of man are to no purpose.

3 What is a man profited by all his work which he does under the sun?

14 I have seen all the works which are done under the sun; all is to no purpose, and desire for wind.

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.
