Ecclesiastes 1:3

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

And this also is a sore evil, that in all points as he came, so shall he go: and what profit hath he that hath laboured for the wind?

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