4:9 Two people are better than one,
because they can reap more benefit from their labor.
4:10 For if they fall, one will help his companion up,
but pity 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?
4:12 Although an assailant may overpower one person,
two can withstand him.
Moreover, a three-stranded cord is not quickly broken.
