Ecclesiastes 4:7-12

7Then I returned, and I saw vanity under the sun. 8There is one alone, and there is not a second; yea, he hath neither child nor brother: yet is there no end of all his labour; neither is his eye satisfied with riches; neither saith he, For whom do I labour, and bereave my soul of good? This is also vanity, yea, it is a sore travail.

9Two are better than one; because they have a good reward for their labour. 10For 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. 11Again, if two lie together, then they have heat: but how can one be warm alone? 12And if one prevail against him, two shall withstand him; and a threefold cord is not quickly broken.
