'All is Vanity' in the Bible

"Vanity of vanities," says 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 a chasing after wind.

So I hated life, because the work that is worked under the sun was grievous to me; for all is vanity and a chasing after wind.

For that which happens to the sons of men happens to animals. Even one thing happens to them. As the one dies, so the other dies. Yes, they have all one breath; and man has no advantage over the animals: for all is vanity.

"Vanity of vanities," says the Preacher. "All is vanity!"
