Webster(i)
6 Better is a handful with quietness, than both the hands full with toil and vexation of spirit.
7 Then I returned, and I saw vanity under the sun.
8 There is one alone, and there is not a second; yes, he hath neither child nor brother: yet is there no end of all his labor; neither is his eye satisfied with riches; neither saith he, For whom do I labor, and bereave my soul of good? This is also vanity, yes, it is a grievous labor.
