A loud voice from the temple tells the seven angels to pour out on the earth the seven bowls of God's wrath. The first bowl produces harmful and painful sores on those who have the mark of the beast and worship its image. The second turns the sea into blood like that of a corpse, and every living thing in it dies. The third turns the rivers and springs into blood, and the angel of the waters declares that God is just because they shed the blood of saints and prophets; the altar responds that his judgments are true and just (vv. 1-7).
The fourth bowl allows the sun to scorch people with fire, and they blaspheme the name of God and do not repent. The fifth falls on the throne of the beast: its kingdom is plunged into darkness, and people gnaw their tongues in anguish, blaspheme and do not repent of their deeds (vv. 8-11).
The sixth bowl dries up the great river Euphrates to prepare the way for the kings from the east. From the mouth of the dragon, the beast and the false prophet come three unclean spirits like frogs, who go out to the kings of the whole world to gather them for battle on the great day of God the Almighty, at the place called in Hebrew Armageddon. In the midst of it a voice warns that Christ comes like a thief, and blessed is the one who stays awake and keeps his garments (vv. 12-16).
The seventh bowl is poured into the air and from the throne comes a loud voice saying, It is done. There are flashes of lightning, rumblings, thunder and an earthquake such as there had never been. The great city is split into three parts, the cities of the nations fall and God remembers Babylon the great to give her the cup of the wine of his wrath. Islands flee, mountains vanish and great hailstones, each about the weight of a talent, fall from heaven, but people blaspheme God for the plague (vv. 17-21).
