Ecclesiastes 4:7-9

Revised Standard Version

⁷ Again, I saw vanity under the sun: ⁸ a person who has no one, either son or brother, yet there is no end to all his toil, and his eyes are never satisfied with riches, so that he never asks, “For whom am I toiling and depriving myself of pleasure?” This also is vanity and an unhappy business.

The Value of a Friend
