n°21 / Ecclesiastes 5 :

12The 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.
13There is a sore evil which I have seen under the sun, namely, riches kept for the owners thereof to their hurt.
14But those riches perish by evil travail : and he begetteth a son, and there is nothing in his hand.
