Proverbs28chapter 28

"A poor man that oppresseth the poor is like a sweeping rain which leaveth no food." This is a flash flood. Rain in that country falls hard and short, water pours off bare slopes into wadis, and a torrent can strip terrace soil, tear out young vines, and gut a mud-brick wall in an hour — leaving nothing to harvest. A poor official squeezing his own neighbours does the same kind of damage: total and local.

"He that by usury and unjust gain increaseth his substance, he shall gather it for him that will pity the poor." Israel's law banned charging interest to a fellow Israelite, required the poor man's cloak to be returned by nightfall, and cancelled debts every seventh year. Every one of those rules existed because moneylending was the standard way a family lost its land.

"For the transgression of a land many are the princes thereof" describes political churn — the rapid turnover of rulers that hit the northern kingdom especially hard, where dynasties fell in coups within a generation.

"He that maketh haste to be rich shall not be innocent." Under the monarchy, trade routes, tax farming, and royal contracts made fast fortunes possible in a way village farming never had. The proverb is describing a new temptation, not an old one.
