Deuteronomy 15:1-4

“At the end of every seven years you shall grant a release of debts. And this is the form of the release: Every creditor who has lent anything to his neighbor shall release it; he shall not require it of his neighbor or his brother, because it is called the LORD’s release. Of a foreigner you may require it; but you shall give up your claim to what is owed by your brother, except when there may be no poor among you; for the LORD will greatly bless you in the land which the LORD your God is giving you to possess as an inheritance
