Then I looked on all the works that my hands had done, 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.
For God gives to a man that is good in his sight wisdom, and knowledge, and joy: but to the sinner he gives toil, to gather and to heap up, that he may give to him that is good before God. This also is vanity and vexation of spirit.
There is one alone, and there is not a second; yea, he has neither child nor brother: yet is there no end of all his labor; neither is his eye satisfied with riches; neither says he, For whom do I labor, and bereave my soul of good? This is also vanity, yea, it is a hard toil.
You looked for much, and, lo, it came to little; and when you brought it home, I blew upon it. Why? says the LORD of hosts. Because of my house that is in ruins, and you run every man to his own house.
