What does a man gain from all his labor,at which he toils under the sun?

Yet when I considered all the works that my hands had accomplished and what I had toiled to achieve, I found everything to be futile, a pursuit of the wind; there was nothing to be gained under the sun.

And who knows whether that man will be wise or foolish? Yet he will take over all the labor at which I have worked skillfully under the sun. This too is futile.

So my heart began to despair over all the labor that I had done under the sun.

When there is a man who has labored with wisdom, knowledge, and skill, and he must give his portion to a man who has not worked for it, this too is futile and a great evil.
