Leviticus 25:22-27

²²As you sow in the eighth year, you will still be eating from that harvest, which will last until your harvest in the ninth year.

²³Land must not be permanently sold, because it really belongs to me. To me you are only foreigners and travelers passing through.

²⁴So whatever land you buy to own, you must make arrangements so it can be returned to its original owner.

²⁵If one of your people becomes poor and sells you some of their land, their close family can come and buy back what they have sold.

²⁶However, if they don't have anyone who can buy it back, but in the meantime their financial situation improves and they have enough to buy back the land,

²⁷they will work how many years it has been since the sale, and pay back the balance to the person who bought it, and go back to their property
