'Rich' in the Bible

The sleep of a working man is sweet, whether he eats little or much; but the full stomach (greed) of the rich [who hungers for even more] will not let him sleep.

folly is set in many exalted places and in great dignity while the rich sit in humble places.

Moreover, do not curse the king, even in your bedroom, and in your sleeping rooms do not curse the rich, for a bird of the air will carry the sound and a winged creature will make the matter known.
