Ecclesiastes 4:7 in the King James Version
Then I returned, and I saw vanity under the sun.
Context
6 Better is a handful, with quietness, than two handfuls with labor and chasing after wind.
7 Then I returned and saw vanity under the sun.
8 There is one who is alone, and he has neither son nor brother. There is no end to all of his labor, neither are his eyes satisfied with wealth. “For whom then do I labor and deprive my soul of enjoyment?” This also is vanity. Yes, it is a miserable business.
