Leviticus 25:23-28

23“Land must never be sold permanently, because the land is mine. To me you are strangers without permanent homes.

24People must always have the right to buy their property back.

25If your brother becomes poor and sells some of his property, then the one who can assume responsibility, his nearest relative, must buy back what he sold.

26If a man doesn’t have anyone to buy it back for him, but if he prospers and earns enough to buy it back himself,

27he must count the years from its sale. Then he will pay what is left to the man to whom he sold it, and it will be his property again.

28However, if he cannot earn enough to buy it back, what he sold stays in the hands of the buyer until the year of jubilee. In the jubilee it will be released, and he will own it again.
