Jeremiah 49:1-2

1Concerning 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 Gad And [why do] his people live in the cities [of Gad]?

2Therefore behold, the days are coming,” says the Lord, “When I will cause an alarm of war to be heard Against 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.
