Ecclesiastes 4:9–12

Two are better than one, because they have a good reward for their labor. For if they fall, the one will lift up his fellow; but woe to him who is alone when he falls, and doesn’t have another to lift him up. Again, if two lie together, then they have warmth; but how can one keep warm alone? If a man prevails against one who is alone, two shall withstand him; and a threefold cord is not quickly broken.
