2. What should be the punishment of Moab for this sin; because they triumphed in the overthrow of Judah, their country shall be in like manner overthrown with that of the Ammonites, who were guilty of the same sin (v. 9, 10): "I will open the side of Moab, will uncover its shoulder, will take away all its defences, that it may become an easy prey to any that will make a prey of it." (1.) See here how it shall be exposed; the frontier-towns, that were its strength and guard, shall be demolished by the Chaldean forces, and laid open. Some of the cities are here named, which are said to be the glory of the country, which they trusted in, and boasted of as impregnable; these shall decay, be deserted, or betrayed, or fall into the enemies' hands, so that Moab shall lie exposed, and whoever will may penetrate into the heart of the country. Note, Those who glory in any other defence and protection than that of the divine power, providence, and promise, will sooner or later see cause to be ashamed of their glorying. (2.) See here to whom it shall be exposed: The men of the east, when they come to take possession of the country of the Ammonites, shall seize that of the Moabites too. God, the Lord of all lands, will give them that land; for the kingdoms of men he gives to whomsoever he will. The Arabians, who are shepherds, and live quietly, plain men dwelling in tents, shall by an overruling Providence be put in possession of the land of the Moabites, who are soldiers, men of war, and cunning hunters, that live turbulently. The Chaldeans shall get it by war, and the Arabians shall enjoy it in peace. Concerning the Ammonites it is said, They shall no more be remembered among the nations (v. 10), for they had been accessory to the murder of Gedaliah, Jer. xl. 14. But of the Moabites it is said, I will execute judgments upon Moab; they shall feel the weight of God's displeasure, but perhaps not to that degree that the Ammonites shall; however, so far as that they shall know that I am the Lord, that the God of Israel is a God of power, and that his covenant with his people is not broken.
