Hisgalus 19:20

And the Chayyah [Anti-Moshiach] was captured and, with it, the Navi Sheker (the False Prophet), the one having performed the otot (signs) before it, by which he deceived the ones having received the tav (mark) of the Chayyah [Anti-Moshiach] and the ones worshiping its Atzav (idol, image). These two were cast alive into the Agam HaEish (Lake of Fire) burning with gofrit (sulfur).
