Gog will come against Israel, but God will foil and defeat them. They will be carrion for vultures, but God will not hide His face from Israel anymore, restoring them to the land. All will know that Israel's exile was for her sin, and not because the conquerors were so great.
God gives a vision of a new, restored temple on His mountain. An angel measures it all.
God's glory returns and fills the temple, and Ezekiel is supposed to tell Israel about all this so they will be convicted of their sins. The priesthood of Zadok is consecrated to offer sacrifices.
