Leviticus 25:24-29

²⁴You must observe the right of redemption for all the land that you acquire; you must allow the land to be bought back by the family from whom you bought it.

²⁵If your fellow Israelite became poor and for that reason sold some of his property, then his nearest relative may come and buy back the property that he sold to you.

²⁶If a man has no relative to redeem his property, but if he has prospered and has the ability to redeem it,

²⁷then he may calculate the years since the land was sold and repay the balance to the man to whom he sold it. Then he may return to his own property.

²⁸But if he is not able to get the land back for himself, then the land he has sold will remain in the ownership of the one who bought it until the year of Jubilee. At the year of Jubilee, the land will be returned to the man who sold it, and the original owner will return to his property.

²⁹If a man sells a house in a walled city, then he may buy it back within a whole year after it was sold. For a full year he will have the right of redemption.
