Charles Ellicott Commentary Revelation 12:8

"And they prevailed not, neither was their place found any more in heaven." — Revelation 12:8 (ASV)

And prevailed not . . .—Better, And their power failed them, and not even was a place found for them any more in heaven. The result of the war was the dragon’s defeat. The whole power of the evil hosts failed them. There is an inherent weakness in evil: a spot which may be touched upon which all its vaunted strength withers. So complete was the overthrow, that even their place knew them no more. “I went by, and, lo! he was gone; I sought him, but he could nowhere be found.”
