2. The judgments threatened against them for this sin. God will take them to task for it (v. 13): I will stretch out my hand upon Edom. Their country shall be desolate from Teman, which lay in the south part of it; and they shall fall by the sword unto Dedan, which lay north; the desolations of war should go through the nation. (1.) They had taken vengeance, and therefore God will lay his vengeance upon them (v. 14): They shall know my vengeance. Those that will not leave it to God to take vengeance for them may expect that he will take vengeance on them; and those that will not believe and fear his vengeance shall be made to know and feel his vengeance; they shall be dealt with according to God's anger and according to his fury, not according to the weakness of the instruments that are employed in it, but according to the strength of the arm that employs them. (2.) They had taken vengeance on Israel, and God will lay his vengeance on them by the hand of his people Israel. They suffered much by the Chaldeans, which seems to be referred to, Jer. xlix. 8. But besides that there were saviours to come upon Mount Zion, who should judge the mount of Esau (Obad. 21), and Israel's Redeemer comes with dyed garments from Bozrah (Isa. lxiii. 1), this implies a promise that Israel should recover itself again to such a degree as to be in a capacity of curbing the insolence of its neighbours. And we find (1 Mac. v. 3) that Judas Maccabeus fought against the children of Esau in Idumea, gave them a great overthrow, abated their courage, and took their spoil; and Josephus says (Antiq. 13.257), that Hircanus made the Edomites tributaries to Israel. Note, The equity of God's judgments is to be observed when he not only avenges injuries upon those that did them, but by those against whom they were done.
