'All is Vanity' in the Bible

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

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

And I hated life; for the work that is wrought under the sun was grievous unto me; for all is vanity and pursuit of the wind.

For what befalleth the children of men befalleth beasts; even one thing befalleth them: as the one dieth, so dieth the other, and they have all one breath; and man hath no pre-eminence above the beast: for all is vanity.

Vanity of vanities, saith the Preacher: all is vanity.
