Leviticus 25:30

³⁰if he again-buyeth (it) not, and the circle of the year is passed, the buyer shall wield it, and his heirs into without end, and it shall not be able to be again-bought, yea, in the jubilee. (but if he buyeth it not back, and the circle of the year is passed, the buyer, and his heirs, shall own it forever, and it shall not be able to be bought back, yea, even in the Jubilee Year.)
