Deuteronomy 24:12-15

24:12 If the person is poor you may not use what he gives you as security for a covering. 24:13 You must by all means return to him at sunset the item he gave you as security so that he may sleep in his outer garment and bless you for it; it will be considered a just deed by the Lord your God.

24:14 You must not oppress a lowly and poor servant, whether one from among your fellow Israelites or from the resident foreigners who are living in your land and villages. 24:15 You must pay his wage that very day before the sun sets, for he is poor and his life depends on it. Otherwise he will cry out to the Lord against you, and you will be guilty of sin.
