'Dispossessed' in the Bible

Concerning the sons (descendants) of Ammon.Thus says the Lord:“Does Israel have no sons [to reclaim Gad from the Ammonites]?Has he no heir?Why then has Malcam taken possession of GadAnd [why do] his people live in the cities [of Gad]?

“Therefore behold, the days are coming,” says the Lord,“When I will cause an alarm of war to be heardAgainst Rabbah of the Ammonites;And it [along with the high ground on which it stands] will become a desolate heap,And its villages will be set on fire.Then will Israel take possession of his possessors,”Says the Lord.
