‘Moreover the word of Yahweh came to me saying, “Son of man, set your face against Mount Seir, and prophesy against it, and say to it, Thus says the Lord Yahweh, Behold I am against you, O Mount Seir, and I will stretch out my hand against you, and I will make you a desolation and an astonishment. I will lay your cities waste and you will be desolate, and you will know that I am Yahweh.” '
Mount Seir (Edom) had no doubt gloated over what was happening to Judah, but now they learn that it would also happen to them. They too would suffer as Judah had previously done at the hand of Yahweh (compare Ezekiel 33:28; Ezekiel 12:20; Ezekiel 19:7). Their betrayal would not save them from the hand of God. There would be total devastation.
‘Mount Seir' refers especially to the continuation of the Jordan rift valley after it passes the Dead Sea, the land where Petra (Sela) is to be found. It was in that mountainous region that the Edomites lived and revealed their almost perpetual enmity towards Judah and Israel.
