Cyrill of Alexandria
The brutality of the Ammonites is depicted similarly to that of the residents of Damascus, as they too slaughtered the unborn children of Gilead. Their actions were not motivated by a desire to assist others or to exact revenge on behalf of outsiders; rather, they were driven by their own self-interest, seeking to enlarge their territory and expand the reach of their kingdom. This occurred after Judea had faced devastation and the Israelites had suffered a complete defeat, leaving the impression that God was powerless and unable to fulfill His promise of deliverance, rendering His people vulnerable before their foes. Furthermore, upon taking possession of the cities, they dared to mock their sovereign Lord and offered songs of gratitude and praise to their idols. See Am. 1:15
