Chapters 8 and 9 are a vision of Jerusalem's sin. One example: Ezekiel 8:6 "And he said to me, 'Son of man, do you see what they are doing — the utterly detestable things the house of Israel is doing here, things that will drive me far from my sanctuary? But you will see things that are even more detestable.'"
Restoration:
Ezekiel 36:24-26 "For I will take you out of the nations; I will gather you from all the countries and bring you back into your own land. I will sprinkle clean water on you, and you will be clean; I will cleanse you from all your impurities and from all your idols. I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh."
Glory:
Ezekiel 44:4 "Then the man brought me by way of the north gate to the front of the temple. I looked and saw the glory of the Lord filling the temple of the Lord, and I fell face down."
