Revelation 16:12-14

12The sixth angel poured out his bowl over the great river Euphrates; and its water was dried up, to prepare the way for the kings from the east.

13Then I saw—coming from the dragon’s mouth and from the beast’s mouth and from the false prophet’s mouth—three unclean spirits like frogs.

14For they are demonic spirits performing miraculous signs, who go out to the kings of the whole world—to gather them for battle on the great Day of Elohei Tzva’ot.
