Leviticus 25:30

if it be not redeemed within the space of a full year. — That is, either by the vendor or his son. According to the interpretation which obtained during the second Temple, the phrase “full year” is here used for the benefit of the seller, inasmuch as it gives him the advantage of an intercalary year, when he has an additional month, up to the last day of which he could still effect the redemption. Moreover, as the purchaser sometimes concealed himself towards the end of the year, in order to prevent the seller from redeeming his house, it was enacted that the original proprietor should hand over the redemption money to the public authorities when the purchaser could not be found, break open the doors, and take possession of the house; and if the purchaser died during the year, the vendor could redeem it from his heir.

It shall not go out in the jubile. — If the vendor, however, failed to redeem the house within the prescribed period, it was not to be subject to the laws of jubile like the land, but is to remain for ever the property of the purchaser.
