Ecclesiastes 4:9-12

⁹Two people work better than one; together they can earn a good pay for their labor.

¹⁰For if one falls, the other can lift up his friend. However, sorrow follows the one who is alone when he falls if there is no one to lift him up.

¹¹If two lie down together, they can be warm, but how can one be warm alone?

¹²One man alone can be overpowered, but two can withstand an attack, and a three-strand rope is not quickly broken.
