What profit has he that works in that in which he labors?
In all labor there is profit: but the talk of the lips leads only to poverty.
What profit has a man of all his labor which he takes under the sun?
Then I looked on all the works that my hands had made, and on the labor that I had expended on it: and, behold, all was vanity and like grasping the wind, and there was no profit under the sun.
And this also is a great evil, that just as he came, so shall he go: and what profit has he who has 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 you submit yourselves unto such, and to every one that works with us, and labors.
