Deuteronomy 24:12-14

12If he is a poor man, you must not go to sleep with the security in your possession; 13be sure to return it to him by sunset, so that he may sleep in his own cloak and bless you, and this will be credited to you as righteousness before the LORD your God.

14Do not oppress a hired hand who is poor and needy, whether he is a brother or a foreigner residing in one of your towns.
