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.

As with many common verbs, the meaning of “to say” in the Bible is highly dependent on context. Who is speaking? Who is hearing? What is it about? Is it a command, a message, an apology, instruction? All these things enter into the meaning of “say.” In general, though, “saying” has to do with sharing truth at various levels -- from the most exalted power people can have to perceive the Lord's desires directly to the most basic of orders issued to people at their lowest.
