Ecclesiastes 4:3-8

³And better than both of them is he who hath not yet been, in that he hath not seen the evil work that hath been done under the sun.

⁴And I have seen all the labour, and all the benefit of the work, because for it a man is the envy of his neighbour. Even this is vanity and vexation of spirit.

⁵The fool is clasping his hands, and eating his own flesh:

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.
