Ezekiel 35:14-15

Judgement belongs to God alone. 

He will right every wrong and dry every tear shed by His children. He causes His goodness to reign on the righteous and the unrighteous now but it will not always be so.

Edom may have thought so highly of herself (see Obad. 3) that she believed she could assume the place of privilege her father Esau had lost, once Judah was destroyed. NKJ Bible.

Ezekiel 35:14–15 (NKJV)

¹⁴ ‘Thus says the Lord God: “The whole earth will rejoice when I make you desolate. ¹⁵ As you rejoiced because the inheritance of the house of Israel was desolate, so I will do to you; you shall be desolate, O Mount Seir, as well as all of Edom—all of it! Then they shall know that I am the Lord.” ’

Lamentations 4:21 (NKJV)

²¹ Rejoice and be glad, O daughter of Edom,

You who dwell in the land of Uz!

The cup shall also pass over to you

And you shall become drunk and make yourself naked.

Mount Seir (Hebrew: הַר-שֵׂעִיר; Har Se'ir) also known as Jibāl ash Sharāh, was a mountainous region stretching between the Dead Sea and the Gulf of Aqaba, demarcating the southeastern border of Edom with Judah. It may also have marked the older historical limit of Egypt in Canaan.

Mount Seir was named for Seir the Horite, whose offspring had previously inhabited the area (Genesis 14:6, 36:20). The children of Esau (the Edomites) battled against the Horites and destroyed them (Deuteronomy 2:4-5, 12, 22). It is specifically noted as the place where Esau made his home (Genesis 32:3; 33:14, 16; 36:8; Joshua 24:4).

The prophet Balaam, predicting Israelite victories over the Trans-Jordanian nations at the end of their Exodus from Egypt, stated "Edom shall be a possession; Seir also, his enemies, shall be a possession”.^[3]

Mount Seir is also given as the location where the remnants "of the Amalekites that had escaped" were annihilated by five hundred Simeonites (I Chronicles 4:42-43). In 2 Chronicles 20:22-23, the "inhabitants of Mt Seir", i.e. the Edomites, came along with the Ammonites and Moabites against Jehoshaphat of Judah, however "Yahweh set ambushments" against them, causing their forces to annihilate one another. Mount Seir is also referenced in the prophetic books as a term for Edom, as in Isaiah 21:11, Ezekiel 25:8, 35:10.
