"Two are better than one because they have a good return for their labor.
For if either of them falls, the other will lift up his/her companion.
But sadness to the one who falls when there is not another to lift him up.
And if someone can overpower he/she who is alone, two can resist them.
A string or cord of three strands is not quickly torn apart."
-Ecclesiastes 4:9-10-
