Ecclesiastes 5:9-12

But this is gain for a land in every way: a king committed to cultivated fields. He who loves money will not be satisfied with money, nor he who loves wealth with his income; this also is vanity. When goods increase, they increase who eat them, and what advantage has their owner but to see them with his eyes? Sweet is the sleep of a laborer, whether he eats little or much, but the full stomach of the rich will not let him sleep.
