Hisgalus 16:10-11

And hachamishi (the fifth) [malach, angel] poured out his ke'ara (bowl) on the kes (throne) of the Chayyah [Beast, Anti-Moshiach]; and the Malchut (Kingdom) of the Chayyah (Beast, Anti-Moshiach) became darkened, and in agony they were gnawing their tongues. And they spoke Chillul HASHEM gidufim (blasphemies) against Elohei HaShomayim (the G-d of Heaven) because of their agony and because of their sores, and they did not make teshuva from their ma'asim (deeds).
