2. Mount Seir--that is, Idumea (Ge 36:9). Singled out as badly pre-eminent in its bitterness against God's people, to represent all their enemies everywhere and in all ages. So in Isa 34:5; 63:1-4, Edom, the region of the greatest enmity towards God's people, is the ideal scene of the final judgments of all God's foes. "Seir" means "shaggy," alluding to its rugged hills and forests.
