Ezekiel 35:7-9

Thus I will make Mount Seir most desolate, and cut off from it the one who leaves and the one who returns. And I will fill its mountains with the slain; on your hills and in your valleys and in all your ravines those who are slain by the sword shall fall. I will make you perpetually desolate, and your cities shall be uninhabited; then you shall know that I am the LORD.
