Leviticus 25:23-33

23‘The land shall not be sold permanently, for the land is Mine; you are [only] foreigners and temporary residents with Me.

24So in all the country that you possess, you are to provide for the redemption of the land [in the Year of Jubilee].

25‘If a fellow countryman of yours becomes so poor he has to sell some of his property, then his nearest relative is to come and buy back (redeem) what his relative has sold.

26Or in case a man has no relative [to redeem his property], but he has become more prosperous and has enough to buy it back,

27then he shall calculate the years since its sale and refund the balance to the man to whom he sold it, and so return to his [ancestral] property.

28But if he is unable to redeem it, then what he has sold shall remain in the hands of the purchaser until the Year of Jubilee; but at the Jubilee it shall revert, and he may return to his property.

29‘If a man sells a house in a walled city, then his right of redemption remains valid for a full year after its sale; his right of redemption lasts a full year.

30But if it is not redeemed for him within a full year, then the house that is in the walled city passes permanently and irrevocably to the purchaser throughout his generations. It does not revert back in the Year of Jubilee.

31The houses of the villages that have no surrounding walls, however, shall be considered as open fields. They may be redeemed, and revert in the Year of Jubilee.

32As for the cities of the Levites, the Levites have a permanent right of redemption for the houses in the cities which they possess.

33Therefore, what is [purchased] from the Levites may be redeemed [by a Levite], and the house that was sold in the city they possess reverts in the Year of Jubilee, for the houses in the Levite cities are their [ancestral] property among the Israelites.
