傳道書 4:8

有人孤單無二，無子無兄，竟勞碌不息，眼目也不以錢財為足。他說：「我勞勞碌碌，刻苦自己，不享福樂，到底是為誰呢？」這也是虛空，是極重的勞苦。

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.
