Ecclesiastes 5:10-12

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