Ecclesiastes 4:9-12

⁹Two are better than one because they have a good return for their labor. ¹⁰For if either of them falls, the one will lift up his companion. But woe to the one who falls when there is not another to lift him up. ¹¹Furthermore, if two lie down together they keep warm, but how can one be warm alone? ¹²And if one can overpower him who is alone, two can resist him. A cord of three strands is not quickly torn apart.
