Ecclesiastes 4:8

There is one [alone], and there is not a second; yea, he has neither son nor brother: yet there is no end to all his labour; neither is his eye satisfied with wealth; and for whom do I labour, and deprive my soul of good? this is also vanity, and an evil trouble.

There is one alone, and there is not a second; yea, he hath neither child nor brother: yet is there no end of all his labour; neither is his eye satisfied with riches; neither saith he, For whom do I labour, and bereave my soul of good? This is also vanity, yea, it is a sore travail.

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.
