Ecclesiastes 4:9-12 NKJV

Two  are  better than one, Because they have a good reward for their labor. For if they fall, one will lift up his companion. But woe to him  who is  alone when he falls, For  he has  no one to help him up. Again, if two lie down together, they will keep warm; But how can one be warm  alone?  Though one may be overpowered by another, two can withstand him. And a threefold cord is not quickly broken.
