Ecclesiastes 4:3-8

³Better also than both these is he who has not yet been, who has not seen all the evil work that is done under the sun.

⁴And I saw all labour, and all the diligent work, that this is a man's envy from his neighbour. This is also vanity and waywardness of spirit.

⁵The fool folds his hands together, and eats his own flesh.

⁶Better is a handful of rest than two handfuls of trouble and waywardness of spirit.

⁷So I returned, and saw vanity under the sun.

⁸There is one alone, and there is not a second; yea, he has neither son nor brother: yet there is no end to all his labour; neither is his eye satisfied with wealth; and for whom do I labour, and deprive my soul of good? this is also vanity, and an evil trouble.
