NET

15 As you rejoiced over the inheritance of the house of Israel because it was desolate, so will I deal with you—you will be desolate, Mount Seir, and all Edom—all of it! Then they will know that I am the Lord.’”

Darby

15 As thou didst rejoice at the inheritance of the house of Israel, because it was desolated, so will I do unto thee: thou shalt be a desolation, O mount Seir, and all Edom, the whole of it: and they shall know that I [am] Jehovah.

KJV

15 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.
