Ecclesiastes 5:10-12

Whoever loves money will never have enough money; Whoever loves wealth will not be satisfied with it. This is also useless. The more wealth people have, the more friends they have to help spend it. So what do people really gain? They gain nothing except to look at their riches. Those who work hard sleep in peace; it is not important if they eat little or much. But rich people worry about their wealth and cannot sleep.
