What profit hath he that worketh in that wherein he laboreth?
In all labor there is profit: but the talk of the lips tendeth only to penury.
What profit hath a man of all his labor which he taketh under the sun?
Then I looked on all the works that my hands had wrought, and on the labor that I had labored to do: and, behold, all was vanity and vexation of spirit, and there was no profit under the sun.
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 labored for the wind?
For what is a man profited, if he shall gain the whole world, and lose his own soul? or what shall a man give in exchange for his soul?
that ye submit yourselves unto such, and to every one that helpeth with us, and laboreth.
