49:7-22 The Edomites were old enemies to the Israel of God. But their day is now at hand; it is foretold, not only to warn them, but for the sake of the Israel of God, whose afflictions were aggravated by them. Thus Divine judgments go round from nation to nation; the earth is full of commotion, and nothing can escape the ministers of Divine vengeance. The righteousness of God is to be observed amidst the violence of men.
7. Concerning Edom—a distinct prophecy, copied in part from Obadiah, but with the freedom of one himself inspired and foretelling a later calamity. Obadiah's was fulfilled probably in Sennacherib's time (compare Isa 34:5; Am 1:11); Jeremiah's about the same time as his preceding prophecies (Jer 49:12; Eze 25:12).
wisdom—for which the Arabs and the people of Teman (a city of Edom) in particular, were famed (Ge 36:15; 1Ki 4:30; see Job, everywhere; Ob 8).
vanished—literally, "poured out," that is, exhausted (compare Isa 19:3, Margin) [Maurer]. Or, as the kindred Ethiopic word means, "worn out" [Ludovicus De Dieu].
