29And if a man sell a dwelling house in a town surrounded with a wall, he may redeem it within the full year of the sale of it; within that time shall be its redemption.
30But if it be not repurchased when the whole year is completed, the house that is in the walled town shall belong absolutely to him who bought it for his generations; it shall not go out at the Jubilee.
