Although it seems that this prophecy is directed to Edom, it is actually addressed to Israel. The shared historical background of the Israel and Edom, on one hand, and the habitation of the Edomites to the south of Yehuda, on the other, presented a religious challenge.
The nation’s fear that God preferred Esav prevailed until the beginning of the return to the land. Even after the Second Temple was built by the returnees, the status of the Edomites – the descendants of Esav – caused Am Yisrael to doubt their own status in God’s eyes. This seems to be an echo of the fear that the Divine choice of Yaakov over Esav is not an eternal choice but that God might change His mind. The impression arising from Yehezkel’s response is that the nation feels that perhaps now, following the destruction of the Temple, after it has been made clear that Am Yisrael did not uphold the covenant with God, God will continue His covenant with Avraham via the sons of Esav, rather than through the descendants of Yaakov.
The hostility between Israel and Edom throughout the generations grew even stronger during the years of Yehezkel’s prophecies, owing to the active participation of some Edomites in shedding the blood of Am Yisrael during the Destruction.
To alleviate the fear of the nation, Yehezkel prophesied the destruction and desolation of Edom as a punishment for their abuse of the remnant of Yehuda. The mountains of Israel will be rebuilt on the ruins of Mount Se’ir.
