The spectacle of a prosperous man whose condition is rendered vain by his brotherless, childless isolation.
A second - Any one associated or connected with him.
Compare a saying from the Talmud: “A man without companions is like the left hand without the right.”
7 Then I returned, and I saw vanity under the sun.
8 There 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.
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; for he hath not another to help him up.
11 Again, if two lie together, then they have heat: but how can one be warm alone?
12 And if one prevail against him, two shall withstand him; and a threefold cord is not quickly broken.
