Leviticus 25:25-28

If a person in your country becomes very poor and sells some land, then close relatives must come and buy it back. If there is not a close relative to buy the land back, but if the person makes enough money to be able to buy it back, the years must be counted since the land was sold. That number must be used to decide how much the first owner should pay back the one who bought it. Then the land will belong to the first owner again. But if there is not enough money to buy it back, the one who bought it will keep it until the year of Jubilee. During that celebration, the land will go back to the first owner’s family.
