Ezekiel 36:23-28

I will vindicate the holiness of My great name which has been profaned among the nations, which you have profaned in their midst. Then the nations will know that I am the LORD,” declares the Lord GOD, “when I prove Myself holy among you in their sight. For I will take you from the nations, gather you from all the lands and bring you into your own land. Then I will sprinkle clean water on you, and you will be clean; I will cleanse you from all your filthiness and from all your idols. Moreover, I will give you a new heart and put a new spirit within you; and I will remove the heart of stone from your flesh and give you a heart of flesh. I will put My Spirit within you and cause you to walk in My statutes, and you will be careful to observe My ordinances. You will live in the land that I gave to your forefathers; so you will be My people, and I will be your God.
