Revelation 16:12 In-Context

10 And the fifth poured out his bowl upon the throne of the beast; and his kingdom was darkened; and they gnawed their tongues for pain,
11 and they blasphemed the God of heaven because of their pains and their sores; and they repented not of their works.
12 And the sixth poured out his bowl upon the great river, the [river] Euphrates; and the water thereof was dried up, that the way might by made ready for the kings that [come] from the sunrising.
13 And I saw [coming] out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet, three unclean spirits, as it were frogs:
14 for they are spirits of demons, working signs; which go forth unto the kings of the whole world, to gather them together unto the war of the great day of God, the Almighty.
