'Companion' in the Bible

There is a person without a companion, without even a son or brother, and though there is no end to all his struggles, his eyes are still not content with riches. “So who am I struggling for,” he asks, “and depriving myself from good?” This too is futile and a miserable task.

For if either falls, his companion can lift him up; but pity the one who falls without another to lift him up.
