O inhabitant of Aroer, stand by the way, and espy; ask him that fleeth, and her that escapeth, and say, What is done?
Aroer - on the north bank of the Arnon, a city of Ammon (Deuteronomy 2:36; Deuteronomy 3:12).
O inhabitant of Aroer, stand by the way, and espy; ask him that fleeth ... What is done? As it was on "the way" of the Moabites who fled into the desert, its inhabitants "ask" what is the occasion of Moab's flight, and so learn the lot that awaits themselves (cf. 1 Samuel 4:3; 1 Samuel 4:16).
