31 But the houses of the villages which have no wall round about them shall be reckoned with the fields of the country: they may be redeemed, and they shall go out in the jubilee. 32 Nevertheless the cities of the Levites, the houses of the cities of their possession, may the Levites redeem at any time. 33 And if one of the Levites redeem, then the house that was sold, and 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 But the field of the suburbs of their cities may not be sold; for it is their perpetual possession.
Matthew Henry's Commentary on Leviticus 25:31-34
Commentary on Leviticus 25:23-34
(Read Leviticus 25:23-34)
If the land were not redeemed before the year of jubilee, it then returned to him that sold or mortgaged it. This was a figure of the free grace of God in Christ; by which, and not by any price or merit of our own, we are restored to the favour of God. Houses in walled cities were more the fruits of their own industry than land in the country, which was the direct gift of God's bounty; therefore if a man sold a house in a city, he might redeem it only within a year after the sale. This encouraged strangers and proselytes to come and settle among them.
