Revelation 16:12-14

New Catholic Bible

¹² The sixth angel poured out his bowl on the great river Euphrates, and its water was dried up to prepare the way for the kings from the East. ¹³ I saw three unclean spirits like frogs^[a] come forth from the mouth of the dragon, from the mouth of the beast, and from the mouth of the false prophet.

¹⁴ These are demonic spirits with the power to work miracles. They were sent to the kings of the entire world to assemble them for battle on the great day of God the Almighty.
