Exodus 22:21-27 - Regulations Regarding Foreigners And The Poor
21 "You are not to wrong or oppress an alien, because you were aliens in the land of Egypt. 22 "You are not to mistreat any widow or orphan. 23 If you do mistreat them, they'll certainly cry out to me, and I'll immediately hear their cry. 24 And I'll be angry and will kill you with swords, and your wives will become widows and your children orphans.
25 "If you loan money to my people, to the poor among you, don't be like a creditor to them and don't impose interest on them.
26 If you take your neighbor's coat as collateral, you are to return it to him by sunset, 27 for it's his only covering; it's his outer garment, for what else can he sleep in? And when he cries out to me, I'll hear him, for I am gracious.
