I. It is promised that the enemies of the church shall be vanquished and brought down, v. 19. Egypt, that old enemy of Israel, and Edom, which had an inveterate enmity to Israel, derived from Esau, these shall be a desolation, a desolate wilderness, no more to be inhabited; they have become the people of God's curse; so the Idumeans were, Isa. xxxiv. 5. No strength nor wealth of a nation is a defence against the judgment of God. But what is the quarrel God has with these potent kingdoms? It is for their violence against the children of Judah, and the injuries they had done them; see Ezek. xxv. 3, 8, 12, 15; xxvi. 2. They had shed the innocent blood of the Jews that fled to them for shelter or were making their escape through their country. Note, The innocent blood of God's people is very precious to him, and not a drop of it shall be shed but it shall be reckoned for. In the last day this earth, which has been filled with violence against the people of God, shall be made a desolation, when it and all the works that are therein shall be burnt up. And, sooner or later, the oppressors and persecutors of God's Israel shall be brought down and laid in the dust, nay, they will at length be brought down and laid in the flames.
