What profit hath man of all his labour wherewith he laboureth under the sun?

Then I looked on all the works that my hands had wrought, and on the labour that it had cost me to do them; and behold, all was vanity and pursuit of the wind, and there was no profit under the sun.

What profit hath he that worketh from that wherein he laboureth?

When goods increase, they are increased that eat them; and what profit is there to the owner thereof, except the beholding of them with his eyes?

And this also is a grievous evil, that in all points as he came so doth he go away, and what profit hath he, in having laboured for the wind?
