Leviticus 25:30-32

New Century Version

³⁰ But if the owner does not buy back the house before a full year is over, it will belong to the one who bought it and to his future sons. The house will not go back to the first owner at Jubilee. ³¹ But houses in small towns without walls are like open country; they can be bought back, and they must be returned to their first owner at Jubilee.

³² “‘The Levites may always buy back their houses in the cities that belong to them.
