As thou didst rejoice at the inheritance of the house of Israel, because it was desolate, so will I do unto thee: thou shalt be desolate, O mount Seir, and all Idumea, even all of it: and they shall know that I am the LORD.
Just as you were happy when you inherited the empty land of Israel, I will make you empty too, Mount Seir and all Idumea. Everyone will know I am the Lord.
