well speaking of the temple in Revelation 11, that whole section is prefaced by John eating a scroll, then the angel guiding him through his visions saying this:
No its not, Rev. 10 has zero to do with Rev. 11, the biggest problem I see is people do not understand Prophecy in general and especially the symbolism of the book of Revelation.
In a quick overview, Rev. 1 is about Jesus' eternal glory, Rev. 2 & 3 is about the Church Age. Everything after this is about the 70th week on earth and/or the Church in heaven during the 70th week. Just like Daniel it is not in chronological order, it has an order to it if you know how to pick it out.
Rev. 4, 5, and 7 are all happening before God's Wrath fall in the middle of the week, the Seals are not Wrath, they point t God's wrath which only comes once the 7 Wax Seals are broken. How does Satan confuse us? He takes one power point like the Seals and conveys they as God's judgment, when they only point to what is coming when the judgment hits. From then on he has most everyone confused.
The Wrath of God is only shown in real time in Rev. 8, 9 and 16 (15 really goes with 16)
Rev. 10, 11, 12, 13, 14, 17, 18 and most of 19 (not counting the Marriage Supper portion after Jesus returns) are "Parenthetical Citation Chapters". They tell of ongoing things inside the exact same timelines as God's Wrath. The Anti-Christ rules for 42 months in Rev. 13, Satan is cast down and chases the woman for 42 months in Rev. 12. The A.C. kills off all Religion in Rev. 17 thus False Religion (The Harlot) also. We see God's Plagues against the whole world (Babylon) in Rev. 18.
Meanwhile Rev. 10 is understood easier when we realize their are only 7 Judgments and 7 = Divine Completion, the Seals are unlocking the Sealed Scroll Judgments, the 7 Vials emit from the 7th Trump. Now Rev. 10 makes sense, after the 7 Thunders (Trumps) sound time will be no more [as we know it], meaning Jesus takes over. This is why swallowing the book was both bitter and sweet, Bitter because a billion or billions of people will have to be killed, and because Judgment brings us into an everlasting relationship with God/Jesus.
Revelation 10:11
"You must prophesy again about many peoples, nations, tongues, and kings."
so Revelation 11, immediately following, seems to me to definitely be about future events.
future meaning, after around 95AD - because i think the mountain of evidence is firmly against a 67-69AD date for the book.
John was prophesying with this testament, and he no doubt preached to those on the Island, but Jesus was speaking about the book of Revelation being a Prophetic Utterance unto the nations. I do not think John is one of the two-witnesses. And if he is one of the two-witnesses, that explains it also, but I think its Elijah and Moses as seen at the transfiguration.
Rev. 11 is merely the Two-witnesses having a parameter placed on them, as Jesus did, they come only to the Jews, that is what the "Measurements mean" They are to go to only the Jews who worship in the Temple. So, Rev. 10 covers 42 months, Rev. 11 actually covers 1335 days, the Two-witnesses are the 1335 blessing.
