ECCLESIASTES 4:8-9

⁸There is one that is alone, and he hath not a second; yea, he hath neither son nor brother; yet is there no end of all his labour, neither are his eyes satisfied with riches. For whom then, saith he, do I labour, and deprive my soul of good? This also is vanity, yea, it is a sore travail.

⁹Two are better than one; because they have a good reward for their labour.
