Leviticus 25:29-34 - Release Of Houses
29 And if any one sell a dwelling-house in a walled city, then he shall have the right of redemption up to the end of the year of the sale thereof; for a full year shall he have the right of redemption. 30 But if it be not redeemed until a whole year is complete, then the house that is in the walled city shall be established for ever to him that bought it, throughout his generations: it shall not go out in the jubilee. 31 But the houses in villages that have no wall round about them shall be reckoned as the fields of the country: they may be redeemed, and they shall go out in the jubilee.
32 But as to the cities of the Levites, the houses in the cities of their possession, the Levites shall have a perpetual right of redemption. 33 And if any one redeem from one of the Levites, then the house that was sold, in the city of his possession, shall go out in the jubilee; for the houses of the cities of the Levites are their possession among the children of Israel. 34 And the field of the suburbs of their cities shall not be sold; for it is their perpetual possession.
