'For A Possession' in the Bible

Behold, therefore I will deliver thee to the men of the east for a possession, and they shall set their palaces in thee, and make their dwellings in thee: they shall eat thy fruit, and they shall drink thy milk.

And the five and twenty thousand of length, and the ten thousand of breadth, shall also the Levites, the ministers of the house, have for themselves, for a possession for twenty chambers.
