Ecclesiastes 1:2-3

2 Vanity of vanities, saith the Preacher, vanity of vanities! all is vanity.

3 What profit hath man of all his labour wherewith he laboureth under the sun?

Ecclesiastes 1:14

14 I have seen all the works that are done under the sun, and behold, all is vanity and pursuit of the wind.

Ecclesiastes 1:17

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.
