Revelation 16:11-13

King James Version

¹¹ And blasphemed the God of heaven because of their pains and their sores, and repented not of their deeds.

¹² And the sixth angel poured out his vial upon the great river Euphrates; and the water thereof was dried up, that the way of the kings of the east might be prepared.

¹³ And I saw three unclean spirits like frogs come out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet.
