Ezekiel 37:21-22

then say to them, Thus says the Lord GOD: Behold, I will take the people of Israel from the nations among which they have gone, and will gather them from all around, and bring them to their own land. And I will make them one nation in the land, on the mountains of Israel. And one king shall be king over them all, and they shall be no longer two nations, and no longer divided into two kingdoms.
