In the year of the jubile the field shall return unto him of whom it was bought, even to him to whom the possession of the land did belong.
Leviticus 27:20
And if he will not redeem the field, or if he have sold the field to another man, it shall not be redeemed any more.
Leviticus 25:28
But if he be not able to restore it to him, then that which is sold shall remain in the hand of him that hath bought it until the year of jubile: and in the jubile it shall go out, and he shall return unto his possession.
