They Will Never Be Satisfied. Ecclesiastes 5: 10-12

He who loves money will not be satisfied with money, nor he who loves abundance with its income. This too is vanity. When good things increase, those who consume them increase. So what is the advantage to their owners except to look on? The sleep of the working man is pleasant, whether he eats little or much; but the full stomach of the rich man does not allow him to sleep. Ecclesiastes 5: 10-12
