This brief prophecy, as spoken of in Ezekiel, talks of a time when the Arab people will falsely claim the land of Israel belongs to them.  But in doing so God will punish them severely.  However, it's spoken of elsewhere in books like Isaiah and Jeremiah that a remnant of the Arab people will come through these judgments and become brothers and neighbors of Israel, all worshiping the same God.  Namely Jehovah, the God of Israel.  While the part about the blessing of the remnant of the Arab nations spoken of in other prophecies has yet to be fulfilled, this prophecy, dealing with the claims of the Arabs against Israeli lands is fulfilled.
