Ezekiel 37:22-24
37:22 I will make them one nation in the land, on the mountains of Israel, and one king will rule over them all. They will never again be two nations and never again be divided into two kingdoms.
37:23 They will not defile themselves with their idols, their detestable things, and all their rebellious deeds. I will save them from all their unfaithfulness by which they sinned. I will purify them; they will become my people and I will become their God.
37:24 “‘My servant David will be king over them; there will be one shepherd for all of them. They will follow my regulations and carefully observe my statutes.
