Leviticus 25:27-35

²⁷then he may calculate the years since the land was sold and repay the balance to the man to whom he sold it. Then he may return to his own property.

²⁸But if he is not able to get the land back for himself, then the land he has sold will remain in the ownership of the one who bought it until the year of Jubilee. At the year of Jubilee, the land will be returned to the man who sold it, and the original owner will return to his property.

²⁹If a man sells a house in a walled city, then he may buy it back within a whole year after it was sold. For a full year he will have the right of redemption.

³⁰If the house is not redeemed within a full year, then the house in the walled city will become the permanent property of the buyer and his descendants. It is not to be returned in the year of Jubilee.

³¹But the houses of the villages that have no wall around them will be considered as the field of the land. They may be redeemed, and they must be returned during the year of Jubilee.

³²However, the houses owned by the Levites in their cities may be redeemed at any time.

³³If one of the Levites does not redeem a house he sold, then the house that was sold in the city where it is located must be returned in the year of Jubilee, for the houses of the cities of the Levites are their property among the people of Israel.

³⁴But the fields around their cities may not be sold because they are the permanent property of the Levites.

³⁵If your fellow countryman becomes poor, so that he can no longer provide for himself, then you must help him as you would help a foreigner or anyone else living as an outsider among you.
