25 ' If a fellow countryman of yours becomes so poor he has to sell part of his property , then his nearest kinsman is to come and buy back what his relative has sold . 26 'Or in case a man has no kinsman , but so recovers his means as to find sufficient for its redemption , 27 then he shall calculate the years since its sale and refund the balance to the man to whom he sold it, and so return to his property . 28 'But if he has not found sufficient means to get it back for himself, then what he has sold shall remain in the hands of its purchaser until the year of jubilee ; but at the jubilee it shall revert , that he may return to his property . 29 'Likewise, if a man sells a dwelling house in a walled city , then his redemption right remains valid until a full year from its sale ; his right of redemption lasts a full year . 30 'But if it is not bought back for him within the space of a full year , then the house that is in the walled city passes permanently to its purchaser throughout his generations ; it does not revert in the jubilee .

Matthew Henry's Commentary on Leviticus 25:25-30

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.
