Leviticus 25:23-28

23“The land is not to be permanently sold because it is mine, and you are only aliens and temporary residents on my land.

24You are to allow the redemption of any land you occupy.

25If your brother becomes destitute and sells part of his property, his nearest relative may come and redeem what his brother has sold.

26If a man has no family redeemer, but he prospers and obtains enough to redeem his land,

27he may calculate the years since its sale, repay the balance to the man he sold it to, and return to his property.

28But if he cannot obtain enough to repay him, what he sold will remain in the possession of its purchaser until the Year of Jubilee. It is to be released at the Jubilee, so that he may return to his property.
