When the Lamb broke the seventh seal, there was silence in heaven for about half an hour. -- 8:1

The third angel sounded, and a great star fell from heaven, burning like a torch, and it fell on a third of the rivers and on the springs of waters.  The name of the star is called Wormwood; and a third of the waters became wormwood, and many men died from the waters, because they were made bitter. -- 8:10-11

Then the fifth angel sounded, and I saw a star from heaven which had fallen to the earth; and the key of the bottomless pit was given to him.  He opened the bottomless pit, and smoke went up out of the pit, like the smoke of a great furnace; and the sun and the air were darkened by the smoke of the pit. -- 9:1-2

And in those days men will seek death and will not find it; they will long to die, and death flees from them. -- 9:6

Then the seventh angel sounded; and there were loud voices in heaven, saying, "The kingdom of the world has become the kingdom of our Lord and of His Christ; and He will reign forever and ever." -- 11:15

And the temple of God which is in heaven was opened; and the ark of His covenant appeared in His temple, and there were flashes of lightning and sounds and peals of thunder and an earthquake and a great hailstorm. -- 11:19

And when the dragon saw that he was thrown down to the earth, he persecuted the woman who gave birth to the male child.  But the two wings of the great eagle were given to the woman, so that she could fly into the wilderness to her place, where she was nourished for a time and times and half a time, from the presence of the serpent. -- 12:13-14

So the dragon was enraged with the woman, and went off to make war with the rest of her children, who keep the commandments of God and hold to the testimony of Jesus. -- 12:17

And I saw the seven angels who stand before God, and seven trumpets were given to them.  Another angel came and stood at the altar, holding a golden censer; and much incense was given to him, so that he might add it to the prayers of all the saints on the golden altar which was before the throne.  And the smoke of the incense, with the prayers of the saints, went up before God out of the angel's hand.  Then the angel took the censer and filled it with the fire of the altar, and threw it to the earth; and there followed peals of thunder and sounds and flashes of lightning and an earthquake.  And the seven angels who had the seven trumpets prepared themselves to sound them. -- 8:2-6

Then the voice which I heard from heaven, I heard again speaking with me, and saying, "Go, take the book which is open in the hand of the angel who stands on the sea and on the land."  So I went to the angel, telling him to give me the little book. And he said to me, "Take it and eat it; it will make your stomach bitter, but in your mouth it will be sweet as honey."  I took the little book out of the angel's hand and ate it, and in my mouth it was sweet as honey; and when I had eaten it, my stomach was made bitter.  And they said to me, "You must prophesy again concerning many peoples and nations and tongues and kings. 
-- 10:8-11

It has been given to the nations; and they will tread under foot the holy city for forty-two months.  And I will grant authority to my two witnesses, and they will prophesy for twelve hundred and sixty days, clothed in sackcloth.  These are the two olive trees and the two lampstands that stand before the Lord of the earth.  And if anyone wants to harm them, fire flows out of their mouth and devours their enemies; so if anyone wants to harm them, he must be killed in this way.  These have the power to  shut up the sky, so that rain will not fall during the days of their prophesying; and they have power over the waters to turn them into blood, and to strike the earth with every plague, as often as they desire.  When they have finished their testimony, the beast that comes up out of the abyss will make war with them, and overcome them and kill them.  And their dead bodies will lie in the street of the great city which mystically is called Sodom and Egypt, where also their Lord was crucified.  Those from the peoples and tribes and tongues and nations will look at their dead bodies for three and a half days, and will not permit their dead bodies to be laid in a tomb.  And those who dwell on the earth will rejoice over them and celebrate; and they will send gifts to one another, because these two prophets tormented those who dwell on the earth.  But after the three and a half days, the breath of life from God came into them, and they stood on their feet; and great fear fell upon those who were watching them. -- 11:2-11

A great sign appeared in heaven: a woman clothed with the sun, and the moon under her feet, and on her head a crown of twelve stars; and she was with child; and she cried out, being in labor and in pain to give birth.  Then another sign appeared in heaven: and behold, a great red dragon having seven heads and ten horns, and on his heads were  seven diadems.  And his tail swept away a third of the stars of heaven and threw them to the earth. And the dragon stood before the woman who was about to give birth, so that when she gave birth he might devour her child.  And she gave birth to a son, a male child, who is to rule all the nations with a rod of iron; and her child was caught up to God and to His throne.  Then the woman fled into the wilderness where she had a place prepared by God, so that there she would be nourished for one thousand two hundred and sixty days.
-- 12:1-6

And there was war in heaven, Michael and his angels waging war with the dragon. The dragon and his angels waged war, and they were not strong enough, and there was no longer a place found for them in heaven.  And the great dragon was thrown down, the serpent of old who is called the devil and Satan, who deceives the whole world; he was thrown down to the earth, and his angels were thrown down with him. -- 12:7-9

Then I heard a loud voice in heaven, saying, "Now the salvation, and the power, and the kingdom of our God and the authority of His Christ have come, for the accuser of our brethren has been thrown down, he who accuses them before our God day and night.  And they overcame him because of the blood of the Lamb and because of the word of their testimony, and they did not love their life even when faced with death.  For this reason, rejoice, O heavens and you who dwell in them. Woe to the earth and the sea, because the devil has come down to you, having great wrath, knowing that he has only a short time." -- 12:10-12
