4:9 Two people are better than one,
4:10 For if they fall, one will help his companion up,
but pity 3 the person who falls down and has no one to help him up.
4:11 Furthermore, if two lie down together, they can keep each other warm,
but how can one person keep warm by himself?
two can withstand him.
Moreover, a three-stranded cord is not quickly broken.
