"Two are better than one, because they have a good reward for their labor."
For if they fall, one will lift up his companion.
"Though one may be overpowered by another, two can withstand him."
"And a threefold cord is not quickly broken." [Ecclesiastes 4:9-10,12]
"Where there is no counsel, the people fall; but in the multitude of counselors there is safety."
Because two are better!
