The law of Moses allowed a lender to take a poor man’s cloak as security for a debt. However, the cloak had to be returned before nightfall, because nights were cold (Exodus 22:26–27; Deuteronomy 24:12–13). The law also said that a widow’s clothing must never be taken as security for a debt (Deuteronomy 24:17).
fines: The wealthy also imposed unjust fines. They bribed judges and used their power to prevent the poor, who could not defend themselves, from receiving a fair hearing (Amos 5:12).
