TSK · Ecclesiastes 8:16

It is vain for you to rise up early, to stay up late, eating the bread of toil; for he gives sleep to his loved ones.

I applied my heart to know wisdom, and to know madness and folly. I perceived that this also was a chasing after wind.

There is one who is alone, and he has neither son nor brother. There is no end to all of his labor, neither are his eyes satisfied with wealth. "For whom then, do I labor, and deprive my soul of enjoyment?" This also is vanity. Yes, it is a miserable business.

I turned around, and my heart sought to know and to search out, and to seek wisdom and the scheme of things, and to know that wickedness is stupidity, and that foolishness is madness.

All this have I seen, and applied my mind to every work that is done under the sun. There is a time in which one man has power over another to his hurt.
