Ecclesiastes 4:9

7 Again I saw something meaningless under the sun:

8 There was a man all alone; he had neither son nor brother. There was no end to his toil, yet his eyes were not content with his wealth. “For whom am I toiling,” he asked, “and why am I depriving myself of enjoyment?” This too is meaningless— a miserable business!

9 Two are better than one, because they have a good return for their labor:

10 If either of them falls down, one can help the other up. But pity anyone who falls and has no one to help them up.

11 Also, if two lie down together, they will keep warm. But how can one keep warm alone?
