Leviticus 25:29-34 - Release Of Houses
29 And when a man shall sell the house of dwelling in a walled city, its redemption of it shall be till it was completed: a year of days from its selling shall be its redemption. 30 And if it was not redeemed till the filling up of a complete year, and the house which is in the city, which, if walled, was set forever to him buying it for his generation: it shall not go forth in the jubilee. 31 And the houses of the villages which to them not being walled round about, shall be reckoned for a field of the land: redemption shall be to it, and it shall go forth in the jubilee.
32 And the cities of the Levites, the houses of the cities of their possession, redemption shall be always to the Levites. 33 And whoever shall redeem from the Levites, and the selling of the house and the city of his possession went out in the jubilee; for the houses of the cities of the Levites, this their possession in the midst of the sons of IsraeL 34 And the field of the area of their cities shall not be sold, for it is a possession to them forever.
