Ecclesiastes 5:10-12

10 He who loves silver shall not be satisfied with silver; nor he who loves abundance, with increase: this also is vanity.  11 When goods increase, those who eat them are increased; and what advantage is there to its owner, except to feast on them with his eyes?

12 The sleep of a laboring man is sweet, whether he eats little or much; but the abundance of the rich will not allow him to sleep.
