Two Witnesses and Three Woes

First Woe
When the angel sounds the fifth trumpet, locusts from the bottomless pit ascend upon the earth. This first woe lasts for five months.
10And they had tails like to scorpions, and there were stings in their tails: and their power was to hurt men five months. 11And they had a king over them, which is the angel of the bottomless pit, whose name in the Hebrew tongue is Abaddon, but in the Greek tongue has his name Apollyon. 12One woe is past; and, behold, there come two woes more hereafter. (Rev. 9:10-12)
Both Abaddon and Apollyon mean destroyer. It is a destroying angel from the abyss.

Two Witnesses/Martyrs (Jewish and Gentile Believers)

Prophesy for 1,260 Days
The "Gentiles", Muslims, have had control of the Temple Mount for hundreds of years, and they will continue to control it and tread upon Jerusalem during the Great Tribulation. Some Muslims contest they are not Gentiles because they are circumcised, but all non-Jews are Gentiles. The duration of the Great Tribulation as 42 months also calculated as 1,260 days, so the months have to be 30 day months using the 360-day year calendar, which gives us 3 1/2 years. The two witnesses prophesy wearing sackcloth. Sackcloth is worn during mourning and grief, and during repentance and humiliation.
1And there was given me a reed like to a rod: and the angel stood, saying, Rise, and measure the temple of God, and the altar, and them that worship therein. 2But the court which is without the temple leave out, and measure it not; for it is given to the Gentiles: and the holy city shall they tread under foot forty and two months. 3And I will give power to my two witnesses, and they shall prophesy a thousand two hundred and three score days, clothed in sackcloth. 4These are the two olive trees, and the two candlesticks standing before the God of the earth. (Revelation 11:1-4)
"Winesses" is martus, meaning martyrs. But there were seven candlesticks and no olive trees mentioned in the first few chapters of Revelation, so John is referring to a different prophetic scripture.
2And said to me, What see you? And I said, I have looked, and behold a candlestick all of gold, with a bowl on the top of it, and his seven lamps thereon, and seven pipes to the seven lamps, which are on the top thereof: 3And two olive trees by it, one on the right side of the bowl, and the other on the left side thereof. . . . he shall bring forth the headstone thereof with shoutings, crying, Grace, grace to it. 9The hands of Zerubbabel have laid the foundation of this house . . . the plummet in the hand of Zerubbabel with those seven; they are the eyes of the LORD, which run to and fro through the whole earth. 11Then answered I, and said to him, What are these two olive trees on the right side of the candlestick and on the left side thereof? 12And I answered again, and said to him, What be these two olive branches which through the two golden pipes empty the golden oil out of themselves? . . . 14Then said he, These are the two anointed ones, that stand by the LORD of the whole earth. (Zechariah 4:2-12 edited and emphasized)
The "seven lamps" are the seven-fold Spirit of God (Rev. 4:5) evident in the seven churches ("candlesticks"). The two olive trees in Zechariah 4 were Joshua, the high priest, and Zerubbabel, the governor. The two olive trees are connected with "those seven" of the "house" of "grace" whose "headstone" is Jesus. "Anointed ones" is ben yitshar, meaning anointed sons. The sons are described in the next chapter as the Son of God and the "remnant of her seed".
5And she brought forth a man child, who was to rule all nations with a rod of iron: and her child was caught up to God, and to his throne. . . . 11And they overcame him by the blood of the Lamb, and by the word of their testimony; and they loved not their lives to the death. . . . 17And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ. (Revelation 12:5, 11, 17)
These are the Hebrew and Gentile believers during the Great Tribulation; the two witnesses that have been made "one new man" in Christ (Ephesians 2:11-22). The two witnesses combined constitute the Bride of Christ. The two witnesses are Us. We will be martyred for Our faith and given white robes (5th seal), but We will prophesy of Christ's coming for Us in powerful ways before We die. We will overcome Satan by the blood of Jesus, Our personal testimony, and Our determination to die rather than give up Our faith. We believers hold fast God's commandments and the "testimony" (marturia meaning witness) of Jesus Christ.

Have Miraculous Power
5And if any man will hurt them, fire proceeds out of their mouth, and devours their enemies: and if any man will hurt them, he must in this manner be killed. 6These have power to shut heaven, that it rain not in the days of their prophecy: and have power over waters to turn them to blood, and to smite the earth with all plagues, as often as they will. 7And when they shall have finished their testimony, the beast that ascends out of the bottomless pit shall make war against them, and shall overcome them, and kill them. (Revelation 11:5-7)
Real fire may come from Our mouths, or the Word of God from Our mouths may incense and devour Our enemies from the inside out (Jeremiah 5:14). Elijah was a foreshadow of the Great Tribulation saints, for he prayed it would not rain for 3 1/2 years, and it did not until he prayed that it would (James 5:17-18). Moses and Aaron turned the Nile to blood, and foretold Pharaoh of the plagues about to happen. The Beast of Islam will war against Christians and be victorious and kill them.

Will be Killed and Resurrected; the Second Woe
8And their dead bodies shall lie in the street of the great city, which spiritually is called Sodom and Egypt, where also our Lord was crucified. 9And they of the people and kindreds and tongues and nations shall see their dead bodies three days and an half, and shall not suffer their dead bodies to be put in graves. 10And they that dwell on the earth shall rejoice over them, and make merry, and shall send gifts one to another; because these two prophets tormented them that dwelled on the earth. 11And after three days and an half the spirit of life from God entered into them, and they stood on their feet; and great fear fell on them which saw them. 12And they heard a great voice from heaven saying to them, Come up here. And they ascended up to heaven in a cloud; and their enemies beheld them. 13And the same hour was there a great earthquake, and the tenth part of the city fell, and in the earthquake were slain of men seven thousand: and the remnant were affrighted, and gave glory to the God of heaven. 14The second woe is past; and, behold, the third woe comes quickly. (Revelation 11:8-14)
New York City is the most populous city of the United States ("great city"), and it is the city with the largest Jewish population outside of Israel (like Egypt housed the Hebrews for hundreds of years). It also has a large homosexual community ("Sodom"). On September 11, 2001 Islamic terrorists flew planes into the Twin Towers; the Muslims in Palestine were shown dancing in the streets and celebrating by passing out candy. This was the "white horse" of the first seal, and something similar may occur soon, beginning the Great Tribulation . Muslims have been slaughtering Christians around the world and leaving their corpses to rot. The "three and a half days" refers to the years of the Great Tribulation. The slaughter will continue and increase until the heavens and earth will shake at the Lord's coming, and our resurrection and rapture unto Him.

The Seventh Trumpet is the Third Woe
15And the seventh angel sounded; and there were great voices in heaven, saying, The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever. 16And the four and twenty elders, which sat before God on their seats, fell on their faces, and worshipped God, 17Saying, We give you thanks, O LORD God Almighty, which are, and were, and are to come; because you have taken to you your great power, and have reigned. 18And the nations were angry, and your wrath is come, and the time of the dead, that they should be judged, and that you should give reward to your servants the prophets, and to the saints, and them that fear your name, small and great; and should destroy them which destroy the earth. 19And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightning, and voices, and thunder, and an earthquake, and great hail. (Revelation 11:1-19)
Then We will execute judgment on the wicked with King Jesus in great power and majesty.
