Ecclesiastes 4

Two people can accomplish more than twice as much as one; they get a better return for their labor. If one person falls, the other can reach out and help. But people who are alone when they fall are in real trouble. And on a cold night, two under the same blanket can gain warmth from each other. But how can one be warm alone? A person standing alone can be attacked and defeated, but two can stand back-to-back and conquer.
