Ezekiel 35:12-15

And you shall know that I am the LORD. “I have heard all the revilings that you uttered against the mountains of Israel, saying, ‘They are laid desolate; they are given us to devour.’ And you magnified yourselves against me with your mouth, and multiplied your words against me; I heard it. Thus says the Lord GOD: While the whole earth rejoices, I will make you desolate. As you rejoiced over the inheritance of the house of Israel, because it was desolate, so I will deal with you; you shall be desolate, Mount Seir, and all Edom, all of it. Then they will know that I am the LORD.
