Ezekiel 35:14-15

The Lord would cause all the earth to rejoice when He made Edom a laughingstock in the world, just as it had rejoiced when Israel became desolate (cf. Ezekiel 36:5). Mount Seir and all of Edom would become absolutely desolate (cf. Ezekiel 36:10). It would not exist when the Lord restored His people to their land. Then the Edomites would learn that Yahweh is God.

"The prediction has been literally fulfilled. Edom was first subjugated by Babylon, then Medo-Persia, and then in 126 B.C. by John Hyrcanus the Hasmonean, who compelled them to become Jews. There is no trace of the Edomites now, although their desolate cities can still be identified, as predicted by Obadiah (Obadiah 1:18) and Jeremiah (Jeremiah 49:13)." [Note: Feinberg, pp. 201-2.]
