Ecclesiastes 4:8-12

There is a man who is alone, neither having son or brother, and there is not an end to all his toil, and his eyes are not satisfied with riches to say, “For whom do I labor and cause my life to lack good things?” Also this is vanity and a burdensome task. Two are better than one, because there is a good reward for their labor together. For if they fall, then one will help up his companion. But woe to him who is alone when he falls and has no one to help him up. Also if two lie down together, then they will keep warm; but how can one keep warm by himself? And if someone might overpower another by himself, two together can withstand him. A threefold cord is not quickly broken.
