Ezekiel 37:22-24

22and I will make them one nation in the land upon the mountains of Israel; and one king shall be king to them all: and they shall be no more two nations, neither shall they be divided into two kingdoms any more at all.

23And they shall not defile themselves any more with their idols, or with their detestable things, or with any of their transgressions; and I will save them out of all their dwelling-places wherein they have sinned, and will cleanse them; and they shall be my people, and I will be their 1God.

24And David my servant shall be king over them; and they all shall have one shepherd: and they shall walk in mine ordinances, and keep my statutes, and do them.
