Thematic Bible: Punishment for oppressive cruelty

Thus says the Lord: For three transgressions of the children of Ammon [descendants of Lot] and for four [for multiplied delinquencies], I will not reverse the punishment of it or revoke My word concerning it, because [the Ammonites] have ripped up women with child in Gilead, that they might enlarge their border. So I will kindle a fire in the wall of Rabbah [in Ammon] and it shall devour the strongholds of it, with shouting in the day of battle, with a tempest in the day of the whirlwind; And their king shall go into exile, he and his princes together, says the Lord.

Concerning and against the Ammonites: Thus says the Lord: Has Israel no sons [to return after their captivity and claim the territory of Gad east of the Jordan which the Ammonites have taken over]? Has [Israel's Gad] no heir? Why then has Milcom [the god the Ammonites call their king] dispossessed and inherited Gad, and [why do] his people dwell in Gad's cities? Therefore 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 [the high ground on which it stands] will become a desolate heap, and its daughter [villages] will be burned with fire. Then will Israel dispossess those who dispossessed him, says the Lord. Wail, O Heshbon [in Moab, just south of Ammon], for Ai [in Ammon] is laid waste! Cry out, you daughter [villages] of Rabbah! Gird yourselves with sackcloth, lament, and run to and fro inside the [sheepfold] enclosures; for Milcom [the god-king] shall go into exile, together with his priests and his princes. read more.
Why do you boast of your valleys? Your valley flows away, O [Ammon] rebellious and faithless daughter, who trusted in her treasures, who said, Who can come against me? Behold, I will bring terror upon you, says the Lord, the Lord of hosts, from all who are round about you; and you will be driven out, each man fleeing straight before him [without thought of his neighbor], and there will be no one to gather together the fugitives.
