Ecclesiastes 4:7-8

4:7 Then I returned, and I saw vanity under the sun. 4:8 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.
