12. then you shall know that I am the Lord.I have heard all the insults you spoke against the mountains of Israel, saying: They are desolate; they have been given to us to devour.
13. You boasted against me with your mouths and used insolent words against me. I heard everything!
14. Thus says the Lord God: Because you rejoiced that the whole land was desolate, so I will do to you.
15. As you rejoiced over the devastation of the heritage of the house of Israel, the same I will do to you: you will become a ruin, Mount Seir, and the whole of Edom, all of it! Then they shall know that I am the Lord.
