Leviticus 25:35-37

35An Israelite may become poor. He may not be able to feed his family. You must help him. You would help a visitor or a foreigner in the same way. You must help the man so that he can continue to live among you.

36The man must not pay back more than you gave to him. You must obey your God.

37The person who is feeding the man might give money or food to him. He must not ask for more back than he gave.
