Exodus 22:22-27

“Do not cheat a widow or an orphan. If you do, and they cry out to me for help, I certainly will hear their cry. And I will be very angry and kill you in war. Then your wives will become widows, and your children will become orphans. “If you lend money to one of my people who is poor, do not treat him as a moneylender would. Charge him nothing for using your money. If your neighbor gives you his coat as a promise for the money he owes you, you must give it back to him by sunset, because it is the only cover to keep his body warm. He has nothing else to sleep in. If he cries out to me for help, I will listen, because I am merciful.
