'Own Possession' in the Bible

And the old inhabiters that dwelt in their own possessions and cities were Israel, the priests, Levites and Nethinims.

For why? The LORD hath chosen Jacob unto himself, and Israel for his own possession.

And in the day that I will make, sayeth the LORD of Hosts, they shall be mine own possession: and I will favour them, like as a man favoureth his own son, that doth him service.
