The houses of the open towns are accorded the advantages of the houses of walled cities, and the advantages of fields: They may be redeemed immediately, and they may be redeemed for the entire twelve months like houses; and they go out in Yovel, and with the deduction of money, like fields. These are the houses of open towns: Two courtyards consisting of two houses each, even if they are surrounded by a wall from the time of Joshua the son of Nun, are judged as houses of open towns.
