Revelation 9 Summary: The Fifth and Sixth Trumpets

Revelation 9 describes the fifth and sixth trumpet judgments, two of the most vivid scenes in the book. A star falls, a pit opens, locust-like creatures emerge, and then four angels are released to lead a vast army across the Euphrates. Readers come to this chapter because it can seem strange and frightening, and a clear summary helps show what John is trying to say to his first readers and to us.

Revelation 9 Summary

The chapter opens with the fifth angel sounding his trumpet. A star falls from the sky, and it is given the key to the bottomless pit. When it opens, smoke rises and darkens the sun and the air, and out of the smoke come locusts with the power of scorpions. They are forbidden to harm the grass or trees, and they are told to target only the people who lack God’s seal on their foreheads. Their torment lasts five months, and it is so painful that people long to die but cannot.

The second half of the chapter moves to the sixth trumpet. A voice from the golden altar before God commands the release of four angels bound at the Euphrates, who have been prepared for an exact hour. They lead an army of two hundred million horsemen, whose breastplates and horses bring fire, smoke and sulfur. A third of humanity is killed, yet the survivors still refuse to repent of their idols, murders, sorceries, immorality and thefts.

So the chapter moves from a painful but limited torment to a devastating war, and it ends on a note of stubborn unbelief. John wants his readers to see that God is still in control of the judgments, even when the scenes are terrifying.

Background and Setting

Revelation is traditionally attributed to John, who writes from the island of Patmos during a period of Roman pressure on the churches of Asia Minor. Most scholars date the book to the late first century, around the reign of Domitian, though some argue for an earlier date in the 60s. The book is addressed to seven churches, and it uses dense symbolism drawn from the Old Testament prophets, especially Ezekiel, Daniel and Joel.

Chapter 9 sits in the middle of the sequence of seven trumpets, which begins in chapter 8. The trumpets form one layer of a larger vision in which God’s judgment falls on a rebellious world while the church is shown to be sealed and protected. Understanding this placement helps readers see that the chapter is part of a carefully ordered revelation, not a random list of disasters.

Revelation 9 Section by Section

Verses 1-6: The Star, the Pit and the Locusts

1 The fifth angel sounded, and I saw a star from the sky which had fallen to the earth. The key to the pit of the abyss was given to him. 2 He opened the pit of the abyss, and smoke went up out of the pit, like the smoke from a burning furnace. The sun and the air were darkened because of the smoke from the pit.

Revelation 9:1-2 (WEB)

4 They were told that they should not hurt the grass of the earth, neither any green thing, neither any tree, but only those people who don’t have God’s seal on their foreheads. 5 They were given power, not to kill them, but to torment them for five months. Their torment was like the torment of a scorpion, when it strikes a person.

Revelation 9:4-5 (WEB)

The chapter begins with a fallen star who receives the key to the abyss. Its opening releases smoke that darkens the sky, and from that smoke come locusts whose stings are compared to scorpions. Their assignment is precise: they may not touch the plants of the earth, and they may only torment people who are not sealed by God. Scripture elsewhere speaks of God’s people being marked for protection, so this limit shows that even the most frightening judgment has boundaries.

The torment lasts five months, which is long enough to be severe but not fatal. John notes that people will seek death and fail to find it. This detail teaches that suffering without relief can drive people to despair, and it presses readers to ask where true hope is found.

Verses 7-12: The Appearance of the Locusts

7 The shapes of the locusts were like horses prepared for war. On their heads were something like golden crowns, and their faces were like people’s faces. 8 They had hair like women’s hair, and their teeth were like those of lions. 9 They had breastplates, like breastplates of iron. The sound of their wings was like the sound of chariots, or of many horses rushing to war.

Revelation 9:7-9 (WEB)

They have over them as king the angel of the abyss. His name in Hebrew is “Abaddon”, but in Greek, he has the name “Apollyon”.

Revelation 9:11 (WEB)

John describes the locusts with a mix of familiar and unfamiliar features: horse-like shapes, golden crowns, human-looking faces, lion-like teeth and iron breastplates. The effect is of something both military and monstrous. Many readers see these images as a picture of an invading force, perhaps reflecting the fear of cavalry armies that would have been known in the ancient world.

The angel of the abyss is named Abaddon in Hebrew and Apollyon in Greek, both words meaning destroyer. The name ties this figure to the language of ruin used across Scripture. The section closes by announcing that the first woe has passed and two more are still to come, which gives the reader a sense of structure and of a judgment that is not yet finished.

Verses 13-16: The Release of the Four Angels

13 The sixth angel sounded. I heard a voice from the horns of the golden altar which is before God, 14 saying to the sixth angel who had the trumpet, “Free the four angels who are bound at the great river Euphrates!” 15 The four angels were freed who had been prepared for that hour and day and month and year, so that they might kill one third of mankind.

Revelation 9:13-15 (WEB)

The sixth trumpet brings a voice from the golden altar before God. It orders the release of four angels bound at the Euphrates, a river that in the Old Testament often marks the border of threatening powers. These angels have been prepared for a precise moment, and they are sent to kill a third of humanity. The exactness of the timing underlines that nothing in this scene is accidental, and that history unfolds according to God’s appointed hour.

The army that follows is said to number two hundred million. John says he heard the number, which suggests that the figure is meant to convey overwhelming scale rather than a literal census of an army.

Verses 17-19: The Horses and Their Power

17 Thus I saw the horses in the vision, and those who sat on them, having breastplates of fiery red, hyacinth blue, and sulfur yellow; and the horses’ heads resembled lions’ heads. Out of their mouths proceed fire, smoke, and sulfur. 18 By these three plagues were one third of mankind killed: by the fire, the smoke, and the sulfur, which proceeded out of their mouths.

Revelation 9:17-18 (WEB)

For the power of the horses is in their mouths, and in their tails. For their tails are like serpents, and have heads, and with them they harm.

Revelation 9:19 (WEB)

The horses have heads like lions and breathe out fire, smoke and sulfur. Their power is located in their mouths and their tails, which are like serpents. John wants readers to see that the weapons of this army are strange and destructive, and that the judgment comes from both ends of the creature. Fire, smoke and sulfur together recall the imagery of Sodom and Gomorrah, which reinforces the message of divine judgment.

The verses also make clear that a third of humanity dies from these three plagues. The sheer weight of this loss is meant to press the reader toward reflection rather than mere spectacle.

Verses 20-21: The Refusal to Repent

20 The rest of mankind, who were not killed with these plagues, didn’t repent of the works of their hands, that they wouldn’t worship demons, and the idols of gold, and of silver, and of brass, and of stone, and of wood; which can’t see, hear, or walk. 21 They didn’t repent of their murders, their sorceries, their sexual immorality, or their thefts.

Revelation 9:20-21 (WEB)

The chapter ends not with the judgment itself but with the response of those who survive. They do not repent of their idols, which cannot see, hear or walk, and they do not turn from murder, sorcery, sexual immorality or theft. This ending is one of the most sobering moments in the book. It shows that suffering alone does not produce repentance, and that hard hearts can persist even in the face of visible judgment.

Key Themes in Revelation 9

• God’s control over judgment: The angels, the locusts and the army all act within limits set by God, who determines the timing and extent of each plague.
• The seal of God: Those who bear God’s seal are protected from the locusts, pointing to the security of God’s people in the midst of judgment.
• The futility of idolatry: The survivors cling to idols that cannot see, hear or walk, showing how empty false worship is when compared to the living God.
• The refusal to repent: Even after terrifying judgment, many people harden their hearts, which is a serious warning about the danger of resisting God’s call.

Lessons From Revelation 9 for Today

Many readers feel uneasy when they encounter scenes of plague and death, and it is natural to ask whether God is cruel. A careful reading of Revelation 9 reminds us that God’s judgments are measured and bounded, and that the protection of his people is part of the same vision. When you face a season of hardship or public upheaval, you can remember that God is not absent from the events around you, even when you cannot see the full pattern.

The chapter also speaks to the way people respond to trouble. It is possible to be surrounded by painful consequences of our choices and still refuse to turn toward God. Someone who keeps returning to a habit that is harming them, or a family that keeps defending a broken pattern, can see something of the same stubbornness in these final verses. The invitation is to soften your heart while there is still time.

Questions for Reflection

• What does the seal on the foreheads of God’s people suggest about how God cares for you in hard seasons?
• Why do you think John emphasizes that the locusts were limited in what they could do?
• In what areas of your life might you be holding onto something that cannot truly help you, as the idols in this chapter cannot?
• How would you respond to a friend who asks whether a chapter like this makes God seem harsh?

A Prayer From Revelation 9

Lord, you hold the keys to every season, and nothing moves outside your timing. When I read about smoke, locusts and great armies, I feel small and uncertain. Remind me that you protect those who belong to you and that your judgments are never careless. Show me any idol I have quietly trusted in place of you, and give me a willing heart to turn back when you call. Keep my eyes on your faithfulness, even when the world around me looks dark. Amen.
