'Vexation' in the Bible

I have seen all the works that are done under the sun; and, behold, all is vanity and vexation of spirit.

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

Then I looked on all the works that my hands had wrought, and on the labour that I had laboured to do: and, behold, all was vanity and vexation of spirit, and there was no profit under the sun.

Therefore I hated life; because the work that is wrought under the sun is grievous unto me: for all is vanity and vexation of spirit.

For what hath man of all his labour, and of the vexation of his heart, wherein he hath laboured under the sun?

For God giveth to a man that is good in his sight wisdom, and knowledge, and joy: but to the sinner he giveth travail, to gather and to heap up, that he may give to him that is good before God. This also is vanity and vexation of spirit.

Again, I considered all travail, and every right work, that for this a man is envied of his neighbour. This is also vanity and vexation of spirit.

Better is an handful with quietness, than both the hands full with travail and vexation of spirit.

There is no end of all the people, even of all that have been before them: they also that come after shall not rejoice in him. Surely this also is vanity and vexation of spirit.

Better is the sight of the eyes than the wandering of the desire: this is also vanity and vexation of spirit.
