17 Iron sharpeneth iron; so a man sharpeneth the countenance of his friend.

9 Two are better than one; because they have a good reward for their labour.10 For if they fall, the one will lift up his fellow; but woe to him that is alone when he falleth, and hath not another to lift him up.11 Again, if two lie together, then they have warmth; but how can one be warm alone?12 And if a man prevail against him that is alone, two shall withstand him; and a threefold cord is not quickly broken.
