9 Two people can accomplish more than twice as much as one; they get a better return for their labor.
10 If one person falls, the other can reach out and help. But people who are alone when they fall are in real trouble.
11 And on a cold night, two under the same blanket can gain warmth from each other. But how can one be warm alone?
12 A person standing alone can be attacked and defeated, but two can stand back-to-back and conquer. Three are even better, for a triple-braided cord is not easily broken.
