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; they shall no longer be two nations, nor shall they ever be divided into two kingdoms again.

23They shall not defile themselves anymore with their idols, nor with their detestable things, nor with any of their transgressions; but I will deliver them from all their dwelling places in which they have sinned, and will cleanse them. Then they shall be My people, and I will be their God.

24“David My servant shall be king over them, and they shall all have one shepherd; they shall also walk in My judgments and observe My statutes, and do them.
