Ecclesiastes 4:6-8

New Revised Standard Version, Anglicised

⁷ Again, I saw vanity under the sun: ⁸ the case of solitary individuals, without sons or brothers; yet there is no end to all their toil, and their eyes are never satisfied with riches. ‘For whom am I toiling’, they ask, ‘and depriving myself of pleasure?’ This also is vanity and an unhappy business.
