Leviticus 25:25-30

25If your brother becomes destitute and sells part of his property, his nearest relative may come and redeem what his brother has sold.

26If a man has no family redeemer, but he prospers and obtains enough to redeem his land,

27he may calculate the years since its sale, repay the balance to the man he sold it to, and return to his property.

28But if he cannot obtain enough to repay him, what he sold will remain in the possession of its purchaser until the Year of Jubilee. It is to be released at the Jubilee, so that he may return to his property.

29“If a man sells a residence in a walled city, his right of redemption will last until a year has passed after its sale; his right of redemption will last a year.

30If it is not redeemed by the end of a full year, then the house in the walled city is permanently transferred to its purchaser throughout his generations. It is not to be released on the Jubilee.
