Ezekiel 37:21-22

21you are to tell them that this is what the Lord GOD says: ‘I will take the Israelites out of the nations to which they have gone, and I will gather them from all around and bring them into their own land. 22I will make them one nation in the land, on the mountains of Israel, and one king will rule over all of them. Then they will no longer be two nations and will never again be divided into two kingdoms.
