Ezekiel 37:22-24

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.

23They will never again be defiled with their idols, their detestable things or with any of their transgressions. I will save them out of all their dwellings in which they sinned. I will purify them. Then they will be My people and I will be their God.

24My servant David will be king over them. They will all have One Shepherd. They will walk in My ordinances and observe My rulings and do them.
