Halakhah su Numeri 36:7

Fields of holding are those that came as an inheritance to each Israelite in the division of the Land, as well as anyone who merited and had his holding added to, due to shifts in the possession by a daughter that inherits possession. As it is a well-known thing that "and the possession should not move" (Numbers 36:7), was only stated about that generation alone. These are the ones called the fields of holding, and their laws are a novelty from the Torah - differing from other lands for the purposes of redemption: As a field of holding can be redeemed by the seller or its redeemer after two years, against the will of the buyer; whereas other fields - which are called a purchased field - can only be redeemed with the buyers consent, [or else] they stay with the buyer until the Jubilee.
