Deuteronomy 15:1-5

“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— only if you carefully obey the voice of the LORD your God, to observe with care all these commandments which I command you today.
