Against Moab thus saith the LORD of hosts, the God of Israel; Woe unto Nebo! for it is spoiled: Kiriathaim is confounded and taken: Misgab is confounded and dismayed. Against Moab - This was delivered some time after the destruction of Jerusalem. The Moabites were in the neighborhood of the Ammonites, and whatever evils fell on the one would naturally involve the other. See Isaiah 15:1-9 and Isaiah 16:1-14 on this same subject.
Wo unto Nebo! for it is spoiled - This was a city in the tribe of Reuben, afterwards possessed by the Moabites. It probably had its name from Nebo, one of the principal idols of the Moabites.
Kiriathaim - Another city of the Moabites.
Misgab is confounded - There is no place of this name known, and therefore several learned men translate המשגב hammisgab, literally, The high tower, or fortress, which may apply to Kiriathaim, or any other high and well-fortified place.
