Matthew Poole and continuators on Judges 21:17

17 And they said, There must be an inheritance for them that be escaped out of Benjamin , that a tribe be not destroyed out of Israel.

The Inheritance promised by Iacob and Moses, and given by Ioshua to the Tribe of Benjamin, doth all of it belong to those few which remain of that Tribe, and cannot be Possessed by any other Tribe; and therefore we are obliged to procure Wives for them all, that they may make up this breach, and be capable of Possessing and managing all their Land: that this Tribe, and their Inheritance may not be confounded with, or swallowed up by any of the rest. Heb. the inheritance (to wit, belonging to the whole Tribe of Benjamin) is, or belongs to them that be escaped of Benjamin.
