Ezekiel 37:21-22

21“Then say to them, thus says Adonai Elohim: ‘Behold, I will take Bnei-Yisrael from among the nations, where they have gone. I will gather them from every side 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 be king to them all. They will no longer be two nations and never again be divided into two kingdoms.
