Ecclesiastes 4:3-5

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.
