Apocalypse Explained # 733
733. Verses 7, 8. And there was war in heaven, Michael and his angels fought with the dragon, and the dragon fought and his angels. And they prevailed not, and their place was not found anymore in heaven.
7. "And there was war in heaven," signifies the combat of falsity against truth, and of truth against falsity n. 734; "Michael and his angels fought with the dragon, and the dragon fought and his angels," signifies the combat between those who are for the life of love and charity and for the Divine of the Lord in His Human against those who are for faith alone or faith separate, and are against the Divine of the Lord in His Human n. 735.
8. "And they prevailed not, and their place was not found anymore in heaven," signifies that they were overcome, and that nowhere in the heavens henceforth is there a place that corresponds to the state of their life, which is a state of thought alone, and of no affection of good and truth (n. 736, 737).
Isaiah 31:4
4
For thus says Yahweh to me, "As the lion and the young lion growling over his prey, if a multitude of shepherds is called together against him, will not be dismayed at their voice, nor abase himself for the noise of them, so Yahweh of Armies will come down to fight on Mount Zion and on its heights.
