IV. That their destruction should be inevitable and very remarkable. 1. God hath determined it (v. 12); he hath said it; nay (v. 13), he hath sworn it, that the Edomites shall not go unpunished, but that they shall drink the cup of trembling, which is put into the hands of all their neighbours; even those whose judgment, or doom, was not to drink of the cup, who had not so well deserved it as they had done, nations that had not been such enemies to Israel as they had been, or Israel itself, that was God's peculiar people, and among whom there were many, very many, who kept his ordinances, upon which account they might have expected an exemption; and yet they had been made to drink of the bitter cup; and shall the Edomites think to pass it? No; they shall surely drink of it. Note, When God punishes the less guilty it is folly for the more guilty to promise themselves impunity; and when judgment begins at God's house it will reach the strangers. 2. All the world shall take notice of it (v. 21): The earth is moved, and all the nations are put into a concern, at the noise of their fall; the news of it shall make them tremble. The noise of the outcry is heard to the Red Sea, which flowed upon the coasts of Edom. So loud shall be the shouts of the conquerors and the shrieks of the conquered, and such a mighty noise shall the news of this destruction of Idumea make in the nations, that is shall be heard among the ships that lie in the Red Sea to take in lading (1 Kings ix. 26), and then they shall carry the news of it to the remotest shore. Note, The fall of those who have affected to make a noise with their pomp and power will make so much the greater noise.
