'Rich' in the Bible

The sleep of the laborer [is] pleasant, whether he eats little or much, but the wealth of the rich man does not allow him to rest.

The fool is set in many high places, but the rich sit in lowly places.

Do not curse the king even in your thoughts, and do not curse the rich even in your own bedroom, for a bird of the sky may carry your voice; a winged messenger may repeat your words.
