Ezekiel 35:10-15

10“Because you [descendants of Esau] have said, ‘These two nations [Israel and Judah] and these two lands shall be mine, and we will take possession of them,’ although the Lord was there,

11therefore, as I live,” says the Lord God, “I will deal with you in accordance with the anger and envy you showed because of your hatred for them; and I will make Myself known among them [as Judge] when I judge and punish you.

12Then you will know [without any doubt] that I am the Lord, and that I have heard all your scornful speeches which you have spoken against the mountains of Israel, saying, ‘They have been made a wasteland; they have been given to us as food.’

13So you have boasted and spoken arrogantly against Me, and have multiplied your words against Me; I have heard it.”

14Thus says the Lord God, “While the whole earth rejoices, I will make you a wasteland.

15As you rejoiced over the inheritance of the house of Israel because it was desolate, so I will do to you; you will be a desolate waste, O Mount Seir, and all Edom, all of it. Then they will know [without any doubt] that I am the Lord.” ’
