Ezekiel 37:22-24

22And 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.

23They shall not defile themselves anymore with their idols and their detestable things, or with any of their transgressions. But I will save them from all the backslidings in which they have sinned, and will cleanse them; and they shall be my people, and I will be their God.

24"My servant David shall be king over them, and they shall all have one shepherd. They shall walk in my rules and be careful to obey my statutes.
