Eccl 4:9-12

The Value of a Friend 9Two are better than one, because they have a good reward for their toil.10For if they fall, one will lift up the other; but woe to one who is alone and falls and does not have another to help.11Again, if two lie together, they keep warm; but how can one keep warm alone?12And though one might prevail against another, two will withstand one. A threefold cord is not quickly broken.
