Ezekiel 37:21-22

21and say to them, ‘This is what the Sovereign Lord says: I will take the Israelites out of the nations where they have gone. I will gather them from all around and bring them back into their own land.

22I will make them one nation in the land, on the mountains of Israel. There will be one king over all of them and they will never again be two nations or be divided into two kingdoms.
