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.

29-31. if a man sell a dwelling house in a walled city, then he may redeem it within a whole year after it is sold—All sales of houses were subject to the same condition. But there was a difference between the houses of villages (which, being connected with agriculture, were treated as parts of the land) and houses possessed by trading people or foreigners in walled towns, which could only be redeemed within the year after the sale; if not then redeemed, these did not revert to the former owner at the Jubilee.
