Ecclesiastes 2:11

Remember what my span of life is; For what vanity You have created all the sons of men!

What advantage does man have in all his labor In which he labors under the sun?

I have seen all the works which have been done under the sun, and behold, all is vanity and striving after wind.

And I gave my heart to know wisdom and to know madness and simpleminded folly; I came to know that this also is striving after wind.

Thus I hated all the fruit of my labor for which I had labored under the sun, for I must leave it to the man who will come after me.

For what does a man get in all his labor and in the striving of his heart with which he labors under the sun?

What advantage is there to the worker from that in which he labors?

He who loves money will not be satisfied with money, nor he who loves abundance with its produce. This too is vanity.

This also is a sickening evil—exactly as a man came, so will he go. So what is the advantage to him who labors for the wind?
