Ecclesiastes 1:2-3

2 Vanity of vanities, saith the preacher, vanity of vanities; all [is] vanity.

3 What profit hath a man of all his labor, which he taketh 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 vexation of spirit.

Ecclesiastes 1:17

17 And I gave my heart to know wisdom, and to know madness and folly: I perceived that this also is vexation of spirit.
