Matthew 11:25-30 (NRSV)7 Again, I saw vanity under the sun: 8 the case of solitary individuals, without sons or brothers; yet there is no end to all their toil, and their eyes are never satisfied with riches. “For whom am I toiling,” they ask, “and depriving myself of pleasure?” This also is vanity and an unhappy business.

9 Two are better than one because they have a good reward for their toil. 10 For if they fall, one will lift up the other; but woe to one who is alone and falls and does not have another to help. 11 Again, if two lie together, they keep warm; but how can one keep warm alone? 12 And though one might prevail against another, two will withstand one. A threefold cord is not quickly broken.
