25 “‘If your brother becomes poor, and sells some of his possessions, then his kinsman who is next to him shall come, and redeem that which his brother has sold. 26 If a man has no one to redeem it, and he becomes prosperous and finds sufficient means to redeem it; 27 then let him reckon the years since its sale, and restore the surplus to the man to whom he sold it; and he shall return to his property. 28 But if he isn’t able to get it back for himself, then what he has sold shall remain in the hand of him who has bought it until the Year of Jubilee: and in the Jubilee it shall be released, and he shall return to his property. 29 “‘If a man sells a dwelling house in a walled city, then he may redeem it within a whole year after it has been sold. For a full year he shall have the right of redemption. 30 If it isn’t redeemed within the space of a full year, then the house that is in the walled city shall be made sure in perpetuity to him who bought it, throughout his generations. It shall not be released in the Jubilee.

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.
