Ecclesiastes 5:9-11

⁹A covetous man shall not be satisfied with money: and he that loveth riches shall reap no fruit from them: so this also is vanity.

¹⁰Where there are great riches, there are also many to eat them. And what doth it profit the owner, but that he seeth the riches with his eyes?

¹¹Sleep is sweet to a labouring man, whether he eat little or much: but the fulness of the rich will not suffer him to sleep.
