Ezekiel 37:21-23

21And say unto them, Thus saith the Lord GOD: Behold, I will take the children of Israel from among the nations, whither they be gone, and will gather them on every side, and bring them into their own land:

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:

23neither shall they defile themselves any more with their idols, nor with their detestable things, nor with any of their transgressions: but I will save them out of all their dwelling places, wherein they have sinned, and will cleanse them: so shall they be my people, and I will be their God.
