They overcame him

Revelation 12:11-12 KJV And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives unto the death. [12] Therefore rejoice, ye heavens, and ye that dwell in them. Woe to the inhabiters of the earth and of the sea! for the devil is come down unto you, having great wrath, because he knoweth that he hath but a short time.
