Revelation 11:1-1411 Then I was given a measuring reed like a rod, with these words: "Go and measure God's sanctuary and the altar, and count those who worship there. 2 But exclude the courtyard outside the sanctuary. Don't measure it, because it is given to the nations, and they will trample the holy city for 42 months. 3 I will empower my two witnesses, and they will prophesy for 1,260 days, dressed in sackcloth." 4 These are the two olive trees and the two lampstands that stand before the Lord of the earth. 5 If anyone wants to harm them, fire comes from their mouths and consumes their enemies; if anyone wants to harm them, he must be killed in this way. 6 These men have the power to close the sky so that it does not rain during the days of their prophecy. They also have power over the waters to turn them into blood, and to strike the earth with any plague whenever they want.
7 When they finish their testimony, the beast that comes up out of the abyss will make war with them, conquer them, and kill them. 8 Their dead bodies will lie in the public square of the great city, which is called, prophetically, Sodom and Egypt, where also their Lord was crucified. 9 And representatives from the peoples, tribes, languages, and nations will view their bodies for three and a half days and not permit their bodies to be put into a tomb. 10 Those who live on the earth will gloat over them and celebrate and send gifts to one another, because these two prophets tormented those who live on the earth.
11 But after the three and a half days, the breath of life from God entered them, and they stood on their feet. So great fear fell on those who saw them. 12 Then they heard a loud voice from heaven saying to them, "Come up here." They went up to heaven in a cloud, while their enemies watched them. 13 At that moment a violent earthquake took place, a tenth of the city fell, and 7,000 people were killed in the earthquake. The survivors were terrified and gave glory to the God of heaven. 14 The second woe has passed. Take note: the third woe is coming quickly!
Revelation 11:1-14 gives us more information regarding the first half of the tribulation. First John is told to measure the temple but exclude the outside sanctuary. The outside sanctuary was a place where non-Jews could enter the temple area. John's instructions were to measure the holiest and holiest of holies. Measurements were taken as a consideration before taking possession so it seems that God is preparing to arrive by measuring the temple. God further explains that the holy city (Jerusalem) will be trampled by the nations of world for 42 months, or 3 1/2 years.
God ensures that he will have a presence in his city in if its going to be tramped under for 42 months.To that end, he provides two witnesses dressed in sackcloth. Sackcloth in the old testament is a sign of morning, people wore those when they were repenting before God or mourning over a lost one. Quite a bit of speculation has gone on regarding these two witnesses. Some postulate that it could be Moses and Elijah since both servants of God did not finish their ministry. Moses did not enter into the holy land, and Elijah had not tasted death but rather was taken up into heaven. An argument can also be made that its Enoch and Elijah since neither person died but was taken up to God. Irregardless of who exactly it is, we can be sure they are witnesses for the Most High and have been granted supernatural power.
Revelation 11:5-6
5 If anyone wants to harm them, fire comes from their mouths and consumes their enemies; if anyone wants to harm them, he must be killed in this way. 6 These men have the power to close the sky so that it does not rain during the days of their prophecy. They also have power over the waters to turn them into blood, and to strike the earth with any plague whenever they want.
We also see that God will be protecting them for the first 3 1/2 years so they can pronounce God's judgment and call to repentence. Like Elijah in the old testament they have the power to shut the sky and cause a drought (another argument that it could be Elijah).
Revelation 11:7-10
7 When they finish their testimony, the beast that comes up out of the abyss will make war with them, conquer them, and kill them. 8 Their dead bodies will lie in the public square of the great city, which is called, prophetically, Sodom and Egypt, where also their Lord was crucified. 9 And representatives from the peoples, tribes, languages, and nations will view their bodies for three and a half days and not permit their bodies to be put into a tomb. 10 Those who live on the earth will gloat over them and celebrate and send gifts to one another, because these two prophets tormented those who live on the earth.
Once their ministry comes to end in 42 months, God lifts the veil of protection and evil seemnigly triumphs as they are killed. God also issues some harsh words against Jerusalem because he likens that city to Sodom and Egypt. Once they are martyred people around the world will view the bodies and celebrate their massacre with gifts and parties. This one verse really shows how low and wicked human heart has sunk into evil. The death of two of God's servants causes the people to give gifts like its Christmas.
Revelation 11:11-14
11 But after the three and a half days, the breath of life from God entered them, and they stood on their feet. So great fear fell on those who saw them. 12 Then they heard a loud voice from heaven saying to them, "Come up here." They went up to heaven in a cloud, while their enemies watched them. 13 At that moment a violent earthquake took place, a tenth of the city fell, and 7,000 people were killed in the earthquake. The survivors were terrified and gave glory to the God of heaven. 14 The second woe has passed. Take note: the third woe is coming quickly!
After 3 1/2 days they rise to their feet and are then carried up into heaven. What a commotion that will create. After celebrating the victory over Gods people (or so they thought) God breathes life back into them and brings up into heaven. As result of their evilness God also shakes a Jerusalem with a massive earthquake killing 7,000 people and destroying a portion of the city.
The 3 woes, which make up the 5th, 6th and 7th trumpets of God's judgment. As a review the fifth trumpet is was the locusts sent out to torment those who rejected God, the second woe is partly made up of the 200 million army crossing the Euphrates to wage war and also the result of the massive earthquake in Jerusalem
The 3rd woe is the final trumpet which is about to come.
The beginning of chapter 11 details that while God is pouring is judgment out on the wicked, he still provides them with an avenue to repent and he provides them with messengers to hear about God's salvation and offers to repent. This is more or less resoundly rejected to the point once they are killed the wicked celebrate the deaths like some perverse holiday by exchanging gifts.
