Ezekiel 37:22-24

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.

23They will no longer defile themselves with their idols and vile images or with any of their offenses, for I will save them from all their sinful backsliding, and I will cleanse them. They will be my people, and I will be their God.

24“ ‘My servant David will be king over them, and they will all have one shepherd. They will follow my laws and be careful to keep my decrees.
