Revelation 16:12-16 - The Sixth Bowl

¹² Then the sixth angel emptied his bowl upon the great river Euphrates; and the water in the river was dried up, so that the road for the Kings of the East might be made ready. ¹³ And I saw three foul spirits, like frogs, come from the mouth of the Dragon and from the mouth of the Beast and from the mouth of the false Prophet. ¹⁴ They are the spirits of demons, and perform marvels; they go to kings all over the world, to collect them for the battle on the Great Day of Almighty God.

¹⁵ ('I am coming like a thief! Happy will he be who is on the watch, and keeps his clothing at hand, so that he will not have to walk about unclothed and let men see his nakedness.')

¹⁶ And the spirits collected the kings at the place called in Hebrew 'Har-Magedon.'
