Ecclesiastes 5:10-12

He that loveth silver shall not be satisfied with silver; nor he that loveth abundance, with increase: this also is vanity. When goods increase, they are increased that eat them; and what advantage is there to the owner thereof, save the beholding of them with his eyes? The sleep of a laboring man is sweet, whether he eat little or much; but the fulness of the rich will not suffer him to sleep.
