There is a vanity which is done on the earth, that there are righteous men to whom it happens according to the work of the wicked. Again, there are wicked men to whom it happens according to the work of the righteous. I said that this also is vanity.

then I saw all the work of God, that man can't find out the work that is done under the sun, because however much a man labors to seek it out, yet he won't find it. Yes even though a wise man thinks he can comprehend it, he won't be able to find it.

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.
