聖經:傳道書 4:8

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。 (CUV 和合本)

傳道書 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. (KJV 欽定本)
