Apocalypse Revealed # 694
694. 16:10 Then the fifth angel poured out his bowl upon the throne of the beast. This symbolizes influx into the people's faith.
The angel's pouring out his bowl means, symbolically, here as before, influx, and the throne of the beast means, symbolically, where faith alone reigns. A throne symbolizes a kingdom or realm, and the beast faith alone (nos. 567, 576, 577, 594, 601, 660).
That a throne is also mentioned in connection with the reign of evil and falsity is apparent from the following:
The dragon gave (the beast) its power, its throne, and great authority. (Revelation 13:2)
I know your works, and where you dwell, where Satan's throne is. (Revelation 2:13)
I watched till thrones were cast down, and the Ancient of Days was seated. (Daniel 7:9)
I will overthrow the throne of kingdoms, and... the strength of the kingdoms of the nations. (Haggai 2:22)
(Lucifer said:) "I will exalt my throne above the stars... (Isaiah 14:13)
And elsewhere.
Revelation 13:1
1
Then I stood on the sand of the sea. I saw a beast coming up out of the sea, having ten horns and seven heads. On his horns were ten crowns, and on his heads, blasphemous names.
