The Lord tells Ezekiel to set his face toward Mount Seir, the mountain region of Edom, and prophesy against it. God declares himself against Seir and will leave it desolate and waste. Its cities will be ruins, and they will know that he is the Lord.
The reason is Edom's everlasting hostility toward Israel. It handed the people of Israel over to the power of the sword in the time of their calamity, in the time of their final punishment. Therefore, as the Lord lives, Edom will be given over to bloodshed and bloodshed will pursue it, since it did not hate bloodshed. Seir will be made a desolation and a waste, its roads cut off, and its mountains filled with the slain.
Edom also said that the two nations, Israel and Judah, would be its own and that it would possess them, although the Lord was there. God will act according to the anger and envy with which Edom treated them, and will make himself known among them when he judges it. Edom boasted against the Lord and multiplied its words against him, and the Lord has heard. Because Edom rejoiced over the desolation of Israel's inheritance, the Lord will treat it the same way; Seir will be desolate, and all of Edom, and they will know that he is the Lord.
