The ransom of a man’s life are his riches: but the poor heareth not rebuke.
– Proverbs 13:8
[T]he word for ransom means a price or even a bribe. The word for rebuke in this context likely means a threat. This proverb is obscure but it seems the contrast indicates a rich man is a target for extortion perhaps, whereas the poor man offers no such target and is not bothered with the fear of it. In this sense, the poor man is freer.
