Ecclesiastes 4:6-8

⁶'Better is a handful with quietness, than two handfuls with labour and vexation of spirit.'

⁷And I have turned, and I see a vain thing under the sun:

⁸There is one, and there is not a second; even son or brother he hath not, and there is no end to all his labour! His eye also is not satisfied with riches, and he saith not, 'For whom am I labouring and bereaving my soul of good?' This also is vanity, it is a sad travail.
