Working signs (poiounta shmeia). "Doing signs" (present active participle of poiew). The Egyptian magicians wrought "signs" (tricks), as did Simon Magus and later Apollonius of Tyana.

Unto the war of the great day of God, the Almighty (ei ton polemon th hmera th megalh tou qeou tou pantokratoro). Some take this to be war between nations, like Mark 13:8 , but it is more likely war against God ( Psalms 2:2 ) and probably the battle pictured in Revelation 17:14 ; Revelation 19:19 .
