7Thus will I make Mount Seir most desolate, and cut off from it all that come and go. 8And I will fill your mountains with the bodies your slain men - in your hills, your valleys, and in all your rivers - shall they lie that were killed by the sword. 9I will make you forever desolate, and your cities shall not recover; and you shall know that I am the LORD. 10Because you have said, ‘The lands of Israel and Judah shall be mine, and we will occupy them; what do we care that the LORD is there?!’ 11Therefore, as surely as I live, says the LORD God, I will treat you in accordance with the anger and envy which you have displayed out of your hatred for them; and I will make Myself known among them, when I have judged you. 12And then you shall know that I am the LORD, and that I have heard all these hateful words which you have spoken against the mountains of Israel: ‘They are laid defeated; and are ours to devour. 13Thus with your own mouth you have boasted against Me, and have multiplied your words against Me; I have heard them.

14This is what the LORD God says: “The whole earth will rejoice when I make you desolate. 15As you rejoiced when the inheritance of My people of Israel, was made desolate, so will I do to you; you shall be desolate, Mount Seir, and all of Edom; and they shall know that I am the LORD.
