Revelation 16:11-13

New Revised Standard Version Catholic Edition

¹¹ and cursed the God of heaven because of their pains and sores, and they did not repent of their deeds.

¹² The sixth angel poured his bowl on the great river Euphrates, and its water was dried up in order to prepare the way for the kings from the east. ¹³ And I saw three foul spirits like frogs coming from the mouth of the dragon, from the mouth of the beast, and from the mouth of the false prophet.
