Ezekiel 37:22-24

22I will make them one nation in the land, on the mountains of Israel, and one king will rule over all of them. They will no longer be two nations and will no longer be divided into two kingdoms.

23They will not defile themselves anymore with their idols, their abhorrent things, and all their transgressions. I will save them from all their apostasies by which they sinned, and I will cleanse them. Then they will be my people, and I will be their God.

24My servant David will be king over them, and there will be one shepherd for all of them. They will follow my ordinances, and keep my statutes and obey them.
