|1||Rev. 8:7 The first angel sounded, and there followed hail and fire mingled with blood, and they were cast upon the earth: and the third part of trees was burnt up, and all green grass was burnt up.||Rev. 16:2 And the first went, and poured out his vial upon the earth; and there fell a noisome and grievous sore upon the men which had the mark of the beast, and upon them which worshipped his image.|
|2||Rev. 8:8-9 And the second angel sounded, and as it were a great mountain burning with fire was cast into the sea: and the third part of the sea became blood;  And the third part of the creatures which were in the sea, and had life, died; and the third part of the ships were destroyed.||Rev. 16:3 And the second angel poured out his vial upon the sea; and it became as the blood of a dead man; and every living soul died in the sea.|
|3||Rev. 8:10-11 And the third angel sounded, and there fell a great star from heaven, burning as it were a lamp, and it fell upon the third part of the rivers, and upon the fountains of waters;  And the name of the star is called Wormwood: and the third part of the waters became wormwood; and many men died of the waters, because they were made bitter.||Rev. 16:4-7 And the third angel poured out his vial upon the rivers and fountains of waters; and they became blood.  And I heard the angel of the waters say, You are righteous, O Lord, which are, and were, and shall be, because you have judged thus.  For they have shed the blood of saints and prophets, and you have given them blood to drink; for they are worthy.  And I heard another out of the altar say, Even so, Lord God Almighty, true and righteous are your judgments.|
|4||Rev. 8:12-13 And the fourth angel sounded, and the third part of the sun was smitten, and the third part of the moon, and the third part of the stars; so as the third part of them was darkened, and the day shone not for a third part of it, and the night likewise.  And I beheld, and heard an angel flying through the midst of heaven, saying with a loud voice, Woe, woe, woe, to the inhabiters of the earth by reason of the other voices of the trumpet of the three angels, which are yet to sound!||Rev. 16:8-9 And the fourth angel poured out his vial upon the sun; and power was given unto him to scorch men with fire.  And men were scorched with great heat, and blasphemed the name of God, which has power over these plagues: and they repented not to give him glory.|
|5||Rev. 9:1-12 And the fifth angel sounded, and I saw a star fall from heaven unto the earth: and to him was given the key of the bottomless pit.  And he opened the bottomless pit; and there arose a smoke out of the pit, as the smoke of a great furnace; and the sun and the air were darkened by reason of the smoke of the pit.  And there came out of the smoke locusts upon the earth: and unto them was given power, as the scorpions of the earth have power.  And it was commanded them that they should not hurt the grass of the earth, neither any green thing, neither any tree; but only those men which have not the seal of God in their foreheads.  And to them it was given that they should not kill them, but that they should be tormented five months: and their torment was as the torment of a scorpion, when he striketh a man.  And in those days shall men seek death, and shall not find it; and shall desire to die, and death shall flee from them.  And the shapes of the locusts were like unto horses prepared unto battle; and on their heads were as it were crowns like gold, and their faces were as the faces of men.  And they had hair as the hair of women, and their teeth were as the teeth of lions.  And they had breastplates, as it were breastplates of iron; and the sound of their wings was as the sound of chariots of many horses running to battle.  And they had tails like unto scorpions, and there were stings in their tails: and their power was to hurt men five months.  And 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.  One woe is past; and, behold, there come two woes more hereafter.||Rev. 16:10-11 And the fifth angel poured out his vial upon the seat of the beast; and his kingdom was full of darkness; and they gnawed their tongues for pain,  And blasphemed the God of heaven because of their pains and their sores, and repented not of their deeds.|
|6||Rev. 9:13-21 And the sixth angel sounded, and I heard a voice from the four horns of the golden altar which is before God,  Saying to the sixth angel which had the trumpet, Loose the four angels which are bound in the great river Euphrates.  And the four angels were loosed, which were prepared for an hour, and a day, and a month, and a year, for to slay the third part of men.  And the number of the army of the horsemen were two hundred thousand thousand: and I heard the number of them.  And thus I saw the horses in the vision, and them that sat on them, having breastplates of fire, and of jacinth, and brimstone: and the heads of the horses were as the heads of lions; and out of their mouths issued fire and smoke and brimstone.  By these three was the third part of men killed, by the fire, and by the smoke, and by the brimstone, which issued out of their mouths.  For their power is in their mouth, and in their tails: for their tails were like unto serpents, and had heads, and with them they do hurt.  And the rest of the men which were not killed by these plagues yet repented not of the works of their hands, that they should not worship devils, and idols of gold, and silver, and brass, and stone, and of wood: which neither can see, nor hear, nor walk:  Neither repented they of their murders, nor of their sorceries, nor of their fornication, nor of their thefts.
Rev. 11:1-14 And there was given me a reed like unto a rod: and the angel stood, saying, Rise, and measure the temple of God, and the altar, and them that worship therein.  But the court which is without the temple leave out, and measure it not; for it is given unto the Gentiles: and the holy city shall they tread under foot forty and two months.  And I will give power unto my two witnesses, and they shall prophesy a thousand two hundred and threescore days, clothed in sackcloth.  These are the two olive trees, and the two candlesticks standing before the God of the earth.  And if any man will hurt them, fire proceedeth out of their mouth, and devoureth their enemies: and if any man will hurt them, he must in this manner be killed.  These 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.  And when they shall have finished their testimony, the beast that ascendeth out of the bottomless pit shall make war against them, and shall overcome them, and kill them.  And 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.  And 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.  And they that dwell upon the earth shall rejoice over them, and make merry, and shall send gifts one to another; because these two prophets tormented them that dwelt on the earth.  And after three days and an half the Spirit of life from God entered into them, and they stood upon their feet; and great fear fell upon them which saw them.  And they heard a great voice from heaven saying unto them, Come up here. And they ascended up to heaven in a cloud; and their enemies beheld them.  And 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.  The second woe is past; and, behold, the third woe cometh quickly.
|Rev. 16:12-16 And the sixth angel poured out his vial upon the great river Euphrates; and the water thereof was dried up, that the way of the kings of the east might be prepared.  And I saw three unclean spirits like frogs come out of the mouth of the dragon, and out of the mouth of the beast, and out of the mouth of the false prophet.  For they are the spirits of devils, working miracles, which go forth unto the kings of the earth and of the whole world, to gather them to the battle of that great day of God Almighty.  Behold, I come as a thief. Blessed is he that watcheth, and keepeth his garments, lest he walk naked, and they see his shame.  And he gathered them together into a place called in the Hebrew tongue Armageddon.|
|7||Rev. 11:14-19 The second woe is past; and, behold, the third woe cometh quickly.  And 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.  And the four and twenty elders, which sat before God on their seats, fell upon their faces, and worshipped God,  Saying, 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.  And 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 unto 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.  And the temple of God was opened in heaven, and there was seen in his temple the ark of his testament: and there were lightnings, and voices, and thunderings, and an earthquake, and great hail.||Rev. 16:17-21 And the seventh angel poured out his vial into the air; and there came a great voice out of the temple of heaven, from the throne, saying, It is done.  And there were voices, and thunders, and lightnings; and there was a great earthquake, such as was not since men were upon the earth, so mighty an earthquake, and so great.  And the great city was divided into three parts, and the cities of the nations fell: and great Babylon came in remembrance before God, to give unto her the cup of the wine of the fierceness of his wrath.  And every island fled away, and the mountains were not found.  And there fell upon men a great hail out of heaven, every stone about the weight of a talent: and men blasphemed God because of the plague of the hail; for the plague thereof was exceeding great.|
The time period for the Sounding of the Trumpets is the entirety of the Gospel Age while the time for the Pouring out of the Seven Last Plagues is at the End of the Gospel Age – during the time of Our Lord's Second Presence.
This suggests that all the troubles that arise during the relatively short period of the pouring out of the seven last plagues are the same type of troubles that occurred throughout the Gospel Age – only this time the troubles are concentrated and come all at once. The "great city," "the city of the nations" is not given time to recover from the first of these troubles before the next one comes upon them, and the next, etc., until all seven troubles are upon her at the same time. Then she, like a patient who had one ailment followed too soon by other ailments, is unable to recover and in the end she dies.
