Bible Verses About Unity

"Two are better than one; because they have a good reward for their labour.
For if they fall, the one will lift up his fellow: but woe to him that is alone when he falleth; for he hath not another to help him up. Again, if two lie together,  then they have heat: but how can one be warm alone?"

and through all and in all."

which they have imagined to do."
