'Alone' in the Bible

Consider someone who is alone, having neither son nor brother. There is no end to all of his work, and he is never satisfied with wealth. "So for whom do I work," he asks, "and deprive myself of pleasure?" This, too, is pointless and a terrible tragedy.

If they stumble, the first will lift up his friend but woe to anyone who is alone when he falls and there is no one to help him get up.
