Deuteronomy 15:1-6

At the end of every seventh year, cancel all debts. This is the procedure: Everyone who has lent money to a neighbor writes it off. You must not press your neighbor or his brother for payment: All-Debts-Are-Canceled—GOD says so. You may collect payment from foreigners, but whatever you have lent to your fellow Israelite you must write off. There must be no poor people among you because GOD is going to bless you lavishly in this land that GOD, your God, is giving you as an inheritance, your very own land. But only if you listen obediently to the Voice of GOD, your God, diligently observing every commandment that I command you today. Oh yes—GOD, your God, will bless you just as he promised. You will lend to many nations but won’t borrow from any; you’ll rule over many nations but none will rule over you.
