Revelation chapter 11 takes place during the Tribulation. I think the Message says it very well .
1-2I was given a stick for a measuring rod and told, “Get up and measure God’s Temple and Altar and everyone worshiping in it. Exclude the outside court; don’t measure it. It’s been handed over to non-Jewish outsiders. They’ll desecrate the Holy City for forty-two months.
In the next few verses God is going to send two witnesses. There are three primary viewpoints on the identity of the two witnesses in Revelation 11:3-12: (1) Moses and Elijah, (2) Enoch and Elijah, (3) two unknown believers whom God calls to be His witnesses in the end times. (1) Moses and Elijah are seen as possibilities for the two witnesses due to the witnesses’ power to turn water into blood (Revelation 11:6), which Moses is known for (Exodus chapter 7), and their power to destroy people with fire (Revelation 11:5), which Elijah is known for (2 Kings chapter 1). Also giving strength to this view is the fact that Moses and Elijah appeared with Jesus at the transfiguration (Matthew 17:3-4). Further, Jewish tradition expected Moses and Elijah to return in the future. Malachi 4:5 predicted the return of Elijah, and the Jews believed that God’s promise to raise up a prophet like Moses (Deuteronomy 18:15, 18) necessitated his return.
(2) Enoch and Elijah are seen as possibilities for the two witnesses because they are the two individuals whom God has taken to heaven apart from experiencing death (Genesis 5:23; 2 Kings 2:11). The fact that neither Enoch or Elijah have experienced death seems to qualify them to experience death and resurrection, as the two witnesses experience (Revelation 11:7-12). Proponents of this view claim that Hebrews 9:27 (all men die once) disqualifies Moses from being one of the two witnesses, as Moses has died once already (Deuteronomy 34:5). However, there are several others in the Bible who died twice—e.g., Lazarus, Dorcas, and the daughter of the synagogue ruler—so there is really no reason why Moses should be eliminated on this basis.
View (3) essentially argues that Revelation chapter 11 does not attach any famous identity to the two witnesses. If their identities were Moses and Elijah, or Enoch and Elijah, why would Scripture be silent about this? God is perfectly capable of taking two “ordinary” believers and enabling them to perform the same signs and wonders that Moses and Elijah did. There is nothing in Revelation 11 that requires us to assume a “famous” identity for the two witnesses.
Which view is correct? The possible weakness of (1) is that Moses has already died once, and therefore could not be one of the two witnesses, who die, which would make Moses a contradiction of Hebrews 9:27. Proponents of (1) will argue that all of the people who were miraculously resurrected in the Bible (e.g., Lazarus) later died again. Hebrews 9:27 is viewed, then, as a “general rule,” not a universal principle. There are no clear weaknesses to view (2), as it solves the “die once” problem, and it makes sense that if God took two people to heaven without dying, Enoch and Elijah, it was to prepare them for a special purpose. There are also no clear weaknesses to view (3). All three views are valid and plausible interpretations that Christians can have. The identities of the two witnesses is an issue Christians should not be dogmatic about.
3-6”Meanwhile, I’ll provide my two Witnesses. Dressed in sackcloth, they’ll prophesy for 1,260. These are the two Olive Trees, the two Lampstands, standing at attention before God on earth. If anyone tries to hurt them, a blast of fire from their mouths will incinerate them—burn them to a crisp just like that. They’ll have power to seal the sky so that it doesn’t rain for the time of their prophesying, power to turn rivers and springs to blood, power to hit earth with any and every disaster as often as they want.
7-10”When they’ve completed their witness, the Beast from the Abyss will emerge and fight them, conquer and kill them, leaving their corpses exposed on the street of the Great City spiritually called Sodom and Egypt, the same City where their Master was crucified. For three and a half days they’ll be there—exposed, prevented from getting a decent burial, stared at by the curious from all over the world. Those people will cheer at the spectacle, shouting ‘Good riddance!’ and calling for a celebration, for these two prophets pricked the conscience of all the people on earth, made it impossible for them to enjoy their sins.
11”Then, after three and a half days, the Living Spirit of God will enter them—they’re on their feet!—and all those gloating spectators will be scared to death.”
12-13I heard a strong voice out of Heaven calling, “Come up here!” and up they went to Heaven, wrapped in a cloud, their enemies watching it all. At that moment there was a gigantic earthquake—a tenth of the city fell to ruin, seven thousand perished in the earthquake, the rest frightened to the core of their being, frightened into giving honor to the God-of-Heaven.
14The second doom is past, the third doom coming right on its heels.
Meanwhile up in Heaven…
The Last Trumpet Sounds
15-18The seventh Angel trumpeted. A crescendo of voices in Heaven sang out,
The kingdom of the world is now
the Kingdom of our God and his Messiah!
He will rule forever and ever!
The Twenty-four Elders seated before God on their thrones fell to their knees, worshiped, and sang,
We thank you, O God, Sovereign-Strong,
Who Is and Who Was.
You took your great power
and took over—reigned!
The angry nations now
get a taste of your anger.
The time has come to judge the dead,
to reward your servants, all prophets and saints,
Reward small and great who fear your Name,
and destroy the destroyers of earth.
19The doors of God’s Temple in Heaven flew open, and the Ark of his Covenant was clearly seen surrounded by flashes of lightning, loud shouts, peals of thunder, an earthquake, and a fierce hailstorm.
Before the sounding of the seventh and last trumpet, there is the usual demand of attention. The saints and angels in heaven know the right of our God and Saviour to rule over all the world. But the nations met God’s wrath with their own anger. It was a time in which he was beginning to reward his people’s faithful services, and sufferings; and their enemies fretted against God, and so increased their guilt, and hastened their destruction. By the opening the temple of God in heaven, may be meant, that there was a more free communication between heaven and earth; prayer and praises more freely and frequently going up, graces and blessings plentifully coming down. But it rather seems to refer to the church of God on earth. In the reign of antichrist, God’s law was laid aside, and made void by traditions and decrees; the Scriptures were locked up from the people, but now they are brought to the view of all. This, like the ark, is a token of the presence of God returned to his people, and his favour toward them in Jesus Christ, as the Propitiation for their sins. The great blessing of the Reformation was attended with very awful providences; as by terrible things in righteousness God answered the prayers presented in his holy temple now opened.
I hope this helps you. God bless you!!! :):)
