As we begin our study of this judgment it is important to remember that these last three trumpets were called “woes” (8:13) to draw our attention to the increased intensity of these judgments as the Tribulation moves closer and closer to its end. Also, remember that one of the purposes of the Tribulation is to unmask Satan’s true character. The fifth trumpet will begin to do this even more clearly. In the church age, Satan often disguises himself as an angel of light with his servants doing likewise (2 Cor. 11:14-15), but from this point on in the Tribulation, the mask will come off and his true colors will be evident for the whole world to see.
This leads us to consider the “star from (out of) heaven which had fallen to earth.” A careful consideration of the context shows us that this star is not a literal meteor or star, but stands symbolically for a person, an angelic creature—specifically Satan.
In more accurate translations, the star is described as “had fallen” (NASB, NIV), looking at the result of a completed event rather than as “fall,” suggesting that John saw the star falling as in the KJV. “Had fallen” is in the perfect tense and points to a fallen condition or state, to what had already occurred with existing results. The event itself is undoubtedly described in chapter 12. That the star is a personality or another angel is suggested by the following:
(1) To this star is given the key to the bottomless pit and the star is called a “him.” Note also the translation “he” in verse 2. In the Greek text, “him” is an intensive, personal pronoun (autos). It is in the dative case and can be masculine (to him) or neuter (to it), but is properly translated “him” because the context is describing a person. Some take the pronouns here to refer to the fifth angel, but the nearest subject to the pronoun and the verb is the star.
(2) The star is seen performing the actions of personality. He opens the abyss (verse 2) which would indicate that the star is in charge of these creatures of the abyss and somehow related to them.
(3) The star is given the ascriptions and appellatives of a person. This is seen in verse 11 which describes the star’s specific relationship to the demonic creatures of the abyss. There he is spoken of as a king, specifically called the Angel of the Abyss, and given names, “Abaddon” and “Apollyon.” That the star of verse 1 is the king and angel of verse 11 seems clearly evident for two reasons: First, the mention of the fallen star in verse one would be meaningless unless he is the actor who opens the pit. Unless this is the case, why call attention to a fallen star. Second, the fact the star was given the key and authority to open the pit in order to bring destruction on the world also fits with the names given to this angel of the abyss. Both names, Abaddon and Apollyon, mean “destruction.”
(4) There is further support for this view in the fact that, in Scripture, angels are called “stars” (Job 38:7) and Satan is specifically referred to as a star (cf. Isa. 14:12 with Luke 10:18). Regarding Isaiah 14:12 as a reference to Satan, Ryrie writes: “star of the morning. Lit., the bright one. Evidently a reference to Satan embodied in the king of Babylon because of Christ’s similar description (Luke 10:18) and because of the inappropriateness of the expressions of verses 13-14 on the lips of any but Satan (cf. 1 Tim. 3:6).”120 While the description in Luke 10:18 does not use the term “star,” the description of seeing Satan “falling from heaven like lightening” can certainly fit the picture of a falling star streaking across the sky like lightning or a beam of light. “Lightning” isastraph, “lightening, brightness, a beam of light.”121
(5) Finally, Luke 8:31, 2 Peter 2:4 and Jude 6 show us that the abyss, here called “the pit of the abyss,” in 2 Peter 2:4, “the pits of darkness,” and in Jude 6, “eternal bonds under darkness” is the abode of a portion of demons or fallen angels. Other Scriptures teach us that Satan is the ruler or king of the fallen angels; they are viewed as his angels (Matt. 12:24, 26; Eph. 2:2; Rev. 12:4, 7). See also John 12:31 and Ephesians 6:12. What we see in these verses fits very well with the facts of Revelation 9.
The opening of the abyss results in a literal darkness, but it is also symbolical of the spiritual darkness that is about to fill the earth and portrays the system and activities of Satan.
Regarding Satan’s fall, consider the following three points:
(1) Satan’s fall is both historic and prophetic. Historically, he lost his position as the anointed cherub when he sinned and rebelled against God. This fall and the reasons for it are recorded in Ezekiel 28:11f and Isaiah 14:12f. Revelation is another reference to this fall. Prophetically, he will be permanently cast out of heaven and restricted to earth in the middle of the Tribulation. Revelation 12:7-17 describes this event that will occur dead center in the Tribulation. It starts the Great Tribulation. While Luke 10:18 shows us the power of Satan has been broken, with the success of the seventy disciples over demons proving that (vs. 17), it may also be prophetic of Satan’s final defeat.
(2) During this interim, Satan evidently has access into God’s presence to accuse believers night and day. One of Satan’s chief purposes in this is to malign the character of God who sentenced him to the lake of fire (cf. Job 1:6-11; Rev. 12:10; Matt. 12:41). Satan is not called “the adversary,” antidikos, “an opponent in a lawsuit,” and “the devil,” diabolos, “the slanderer,” for no reason.
(3) Revelation 9:1-11 does not record the fall itself, but the aftermath of Satan’s fall to earth occurring in the middle of the Tribulation. Knowing that his time is short, he will do all he can to bring about pain and suffering on the earth including the greatest time of anti-Semitism the world has ever known (see Rev. 12:13-17).
Giving the fallen star “the key” obviously stands for authority and power to open the bottomless pit.
“Of the bottomless pit” is literally, “the pit of the abyss.” “Bottomless” is the abussos, “abyss, unfathomable depths.” This word is used Luke 8:31, Rom. 10:7 and in Revelation 9:1, 2, 11; 11:7; 17:8; 20:1, 3. “Pit” is the Greek frear, “pit, well, shaft.”
But what is this abyss?
(1) The abyss is the temporary abode and prison of a portion of the demon hosts where they wait their eternal and final judgment to the lake of fire.
(2) Various descriptions of this place: (a) In 2 Peter 2:4 it is described as “the abode of the judged,” Literally, “having cast them into tartarus” (tartarow, “to hold captive in tartarus”). Tartarus means “the abode of the judged,” and as “pits of darkness.” “Pits” is seiros, “a deep pit as used in storing grain,” and “darkness” is zofos, “blackness.” (b) In Jude 6 it is described as “eternal bonds under darkness.” (c) In Luke 8:31 and Romans 10:7, it is described simply as “the abyss,” abussos, “the place of unfathomable depth.” (d) In Revelation 9:1-2, it is described as “the pit or shaft of the abyss, and (e) as “the spirits now in prison” in 1 Peter 3:19-20.
(3) A study of the above passages show us that the abyss is a place of judgment for demons for specific sin. It is utterly black and the demons there are in total oblivion to the rest of the universe. It is also a place of bondage, a prison from which not even Satan can release them until he is give the key and authority to do so in keeping with God’s sovereign purpose for the Tribulation.
(4) The majority of these bound demons are there because they left their normal habitation and abode. This refers to leaving their heavenly sphere and purpose as designed by God. Some believe this includes whatever is involved in the events of Genesis 6.
(5) It appears that others were cast there by Christ during His ministry on earth according to Luke 8:31-33. In this regard, just some food for thought: (a) According to Luke 11:24f, demons travel and seek habitats in waterless places. (b) The Greek translation in the LXX for the Hebrew word, teJom, “deep, ocean, large body of water,” and for salaJ, “ocean, deep,” is our word abussos. (c) Revelation 21:1 and 22:1f describe conditions of the new heavens and earth in which the only water is the river of life. Evidently, there will be no sea or ocean in the new earth. (d) It is interesting that the specific judgment God used on the antediluvian world, the world involved with the fallen angels called, “sons of God,” in Genesis 6, was the flood. The flood was not merely caused by rain, but by the crust of the earth breaking up with water coming from subterranean levels. Is there some kind of relation between water, the oceans, and the subterranean levels and the abyss? Interestingly, the swine running into the water was certainly a judgment and was perhaps symbolical of the fact that Christ was sending them into the abyss.
In Revelation 9, Satan, the king of the fallen angels or demons, is given the power and authority by God to open the abyss and release these demons on earth as part and instruments of God’s divine wrath.
All the demons including Satan will be bound and thrown into the abyss again at the end of the Tribulation for 1,000 years (Rev. 20:1-3). Satan will be released from his prison at the end of the 1,000 years, and he will come out to deceive the nations. Some will follow him but the King of kings will quickly defeat him and cast him with his demon hosts into the lake of fire forever (Rev. 20:7-10).
The following chart illustrates the history of the imprisonment of demons:
Verse 2. “And he opened …” draws our attention to Satan’s character—cruel, vicious, and hurtful to the core. As soon as the opportunity is presented, he takes advantage of it. He does not need to be coaxed. He simply needs the opportunity—the removal of the restraining hand of God. Remember, as “the adversary,” he is the one who walks about like a roaring lion always in search of someone to devour (1 Pet. 5:8).
“And smoke went up out of the pit … ; and the sun and the air were darkened.” “Air” is the Greek, ahr and refers to the atmosphere about the earth. Earth’s atmosphere will become polluted with the smoke pouring out of the abyss. This will block out the sun and suddenly all will be dark. This is a literal darkness, but is also symbolical of the spiritual darkness that will fall on the earth in the system and activities of Satan and his end time system of the beast.
This demonic activity that will literally fill the atmosphere will be clearly evident to the eyes of men, even the demon creatures themselves. Ironically, according to Ephesians 2:2 and other passages, our atmosphere and the world we live in even now are full of demonic forces and activity, but on the whole, they are hidden to the world. Many do not really believe in a real devil or in demons. Many may be blind to their existence now, but not so in the future.
Verse 3: The appearance of these demonic creatures of the abyss is given in verses seven and following. Here they are simply called locusts with the stinging power of scorpions. Descending out of the abyss, these are demons but they will take on the form described in verses seven and following. This is a literal phenomenon that will occur and it has spiritual significance. In Scripture locusts are associated with divine wrath (Ex. 10:12-20). This is why they are called locusts. But unlike the locusts of history who attack vegetation, these are commanded not to hurt the grass, etc.; their purpose will be to hurt men.
Verse 4: In this verse these demon creatures are told not to do what locusts normally do—attack vegetation. In Old Testament times and throughout history the locust is a symbol of destruction and terror. I have read that they may travel in a column 100 feet deep and up to four miles in length leaving the land stripped bare of all vegetation.122
Who gives this command to hurt only man but not the vegetation? In the light of God’s dealings with Satan in the Book of Job, this is probably God. The only one excluded from this torment of locust are the 144,000 who have the seal of God in their foreheads. We might assume, however, that as far as this plague is concerned, they stand representatively for all believers and that any believer would be spared this torment. Why? This is a judgment upon men who have rejected Christ, not for believers in Jesus Christ, those who had believed the message of the 144,000.
Verse 5: It is interesting to note that again specific limitations are placed on these demonic creatures by God. They are limited as to what and who they may strike (vs. 4), as to how far they may go in the torment (not unto death), and as to how long (five months) (vs. 5).
“Scorpion” is the Greek word skorpios. This was a lobster like vermin some four or five inches long. It had a claw on the end of the tail that secreted a poison when it struck.123 Please notice that these demons are not called scorpions, nor are we told that they look like scorpions, just that they have the power (vs. 3), and torment (vs. 5) of a scorpion. This means they have the power to cause tremendous pain, short of death, but extending for five months.
Verse 6: In this verse we see the effect which will drive men to seek suicide, but they will be unable to accomplish it. Death will elude them. This is astounding and clearly a supernatural restraint of God that stresses and demonstrates His absolute authority or sovereignty. As Ryrie puts it, “Bodies will not sink and drown; poisons and pills will have no effect; and somehow even bullets and knives will not do their intended job.”124
So in addition to the natural plagues that have afflicted the earth, now men are directly attacked and tormented by these demonic creatures.
These verses make it clear that these creatures are not ordinary locusts, and are only called such because of their function in judgment. The same applies, as mentioned above, to their likeness to scorpions. The emphasis is on the capacity to torment and to cause pain.
In their description John lists eight things about their appearance. He begins with the head and moves backward to their tails, the source of their power to inflict torment for the five months. Torment is their sole purpose. The description here defies imagination, but remember, these are demonic creatures that have come from the abyss. They are the worst of the demons of Satan. Whether they take on this form as a demonic-like apparition, or just what happens here we are not told. But they will be real and will inflict terrible torment upon mankind. It will be a literal hell on earth.
This king over the demons is of course Satan. He is called the Angel of the Abyss because he is a fallen angel and because of his own relation to the abyss and to those within it. They are there because they followed his rebellion, he is given the key to release them and he will be bound there himself.
His name given in both Hebrew and Greek means destroyer. This is just another of the many names of Satan given in Scripture that portray his character and activities (cf. 12:9). As the destroyer he is the one chiefly responsible for all the forms of destruction in this life, from the Garden of Eden to the last battle at the end of the Millennium (Gen. 3—Rev. 20). In many ways, the Scripture is in essence a portrait of two, of Satan and his destruction, and the Savior and His deliverance.
With the first woe now past we are informed that the next two woes are still to come. As serious and fearful as the first woe is in its torment, it is only the first. The worst is yet to come. As we shall see in the second woe and have seen in the first, the Tribulation unmasks the true character of Satan in all his evil and cruelty, but it also demonstrates the depravity and rebellion of the human heart. This will especially be seen in this second woe.
Concerning this woe Walvoord says,
For the first time in history all those who do not know the Lord Jesus Christ as Savior will come under demonic possession and affliction. What is true in that hour is also true in some measure today, for there is no deliverance from the power of Satan nor from his affliction apart from salvation in Christ and the delivering power of God.125
Today we are seeing the stages set for this very black and degenerate hour that is portrayed in this sixth trumpet or second woe.
This is the same altar mentioned in 8:3 in the scene of the offering of incense with the prayers of the saints. The voice is probably that of the priestly angel and the implication is that this judgment like the preceding is in answer to the prayers of the saints so persecuted by the beast in the Tribulation.
The sixth angel is instructed to release four angels bound at the River Euphrates. The Euphrates is called great, perhaps not just for its size, but because of its prominence and importance in Scripture.
Verses 14-15 speak of four angels that are bound at the Euphrates River and then released to kill one-third of mankind. The Euphrates is mentioned twice in Revelation, here and in 16:12.
The epithet “great” is used in both occurrences. The entire length is 1780 miles, and it is by far the longest and most important river of western Asia. The Euphrates was the natural boundary separating the nations of the east from Palestine. Its broad stream flowed between Israel and her powerful enemy Assyria. The Euphrates was also the limit of the Roman conquests in that part of the world. We understand, therefore, that the literal Euphrates is here signified, and not the Turkish power.126
Who are these angels? They are fallen angels, demonic spirits similar to those in 16:13-14. The four angels of Revelation 7:1 are good angels who carry out the judgment of God. These, however, appear to be fallen angels because they have been bound. Good angels are never spoken of as bound, unless this is the exception. On the other hand, demonic spirits or fallen angels are bound or will be (cf. Jude 6; 2 Pet. 2:4; Rev. 20:2 with 9:1ff). These, then, are wicked angels prepared by God to be released as a further judgment against a godless, Christ rejecting world.
The expression “For the hour and day and month and year” refers not to the duration of their activity, but to the fact this occurs exactly on the hour of God’s appointment, i.e., the exact hour of the day, month, and year that God ordained it. God raises up both men and demons as His instruments to accomplish His purposes in history. Each acts out of their own volition, according to their schemes and nature, but God, knowing them from eternity past, raises them up in history to carry out His purpose even at the exact hour (cf. Isa. 10:5f; Rom. 9:11-18).
“So that they might kill a third of mankind.” This states their purpose in the plan of God. But just how do they do this? The following verses tell us. They do it through an army of 200,000,000. Earlier one-fourth of the earth’s population is killed in the fourth seal. Now one-third of the remaining population of mankind is wiped out. This means the earth’s total population is reduced by one-half by these two judgments alone and these judgments do not account for all the deaths that will occur. The other judgments also will result in widespread destruction of human life. As Walvoord says, “Never since Noah has such a substantial proportion of the earth’s population come under God’s righteous judgment.”127
Is this literal 200,000,000 man army or a description of an innumerable host? Walter Scott thinks that it should not be taken literally.
We have had the number of the invisible leaders, four; now both the reader and the Seer are informed as to the number of the invading hosts, stated to be “twice ten thousand times ten thousand,” or two hundred millions. This immense host is a number too vast for human conception. The mind gets bewildered in the effort to comprehend such an army which for number surpasses anything ever seen on earth. The unseen chariots of God are similarly numbered (Psa. 68:17) … A literal army consisting of two hundred millions of cavalry need not be thought of. The main idea in the passage is a vast and overwhelming army, one beyond human computation, and exceeding by far any before witnessed.128
Ryrie is of the opinion that this army is made up of demons. He says, “The weapons of this army are fire, smoke, and brimstone (vs. 17) which are weapons of hell and may further indicate that the army is made up of the inhabitants of hell—demons.”129 It is clear that the four angels are the demons, however, it is more likely that this army, like one gathered in 16:14, is a human army already in existence which these demons now cause to move against mankind similar to the work of the three unclean spirits who cause the kings of the earth to gather together for the battle of Armageddon (16:13ff). Walvoord writes:
There is no direct statement as to the origin of this army, but the implication is, from the fact that the angels of verse 14 were bound “in” or at Euphrates, that the army may come from the East. A similar and later development mentioned in Revelation 16:12 following the outpouring of the sixth vial also depicts an invasion from the East. Unless the vials and the trumpets coincide as some believe, these are two different events, possibly two different phases of the same operation. Chronologically the trumpets involved closely succeed one another and their judgments seem to fall like trip-hammer blows as the great Tribulation comes to its close. Whether the army is held to be the literal number mentioned or not, it is clear that this is a massive force of tremendous military power as evidenced in its capacity to slay a third part of the human race. It may be that the army here described continues to fight until the time of the second coming of Christ, and the number slain is the total number involved in the conflict.130
Verses 17-19 describe the army and its tactics or method of warfare. Quite clearly these are not ordinary horsemen or horses. Since this refers to a human army, it is probably best taken as symbolical of modern mechanical warfare. John has never seen tanks or armored vehicles, so he was given a vision of horsemen, as in his day—yet the vision went beyond his day and portrayed modern warfare. The fire, smoke, and brimstone could refer to any number of devices of modern warfare. Again in verse 18 it is mentioned that one-third of mankind will be killed.
Through humanism and a Christ-rejecting society, man has little to look forward to, specifically, the horrible conditions of these two verses. Here we see the harvest, the true results of humanism and the great society the world is seeking to develop—but apart from God and the Lord Jesus Christ. The following three points describe the character of this society and its people.
“And the rest … who were not killed . . did not repent.” One would think by this time men would be crying out for mercy from God in deep repentance, especially since the world will know these all things that are happening are judgments from God (cf. 6:14-17). But no, by now the rest of mankind has become confirmed in their rebellion and depraved ways through the hardening effect of continued negative volition to God.
Significantly, the things they will refuse to repent of are “the works of their own hands.” This demonstrates the extreme humanistic nature of man that has always been evident, but especially in these last days. Men, as we see today, reject the works of God both in creation and in salvation. Man seeks to handle life by what he can do apart from God. But wasn’t this precisely the heart and nature of Satan’s temptation to Eve in Genesis 3?
We should notice that this is a consequence of the refusal to repent. The translation of the NASV “So as not to” represents the conjunction %ina, “in order that” and the negative particle mh, “not.” This may look at a negative purpose or intent, or a negative result or consequence. Theologically, however, both concepts, as mentioned previously, are often involved together. Men often refuse to come to Christ, even though salvation is by grace, because they want to continue to pursue their present lifestyle of sin. As our Lord teaches us in the Gospel of John:
John 3:19-21 And this is the judgment, that the light is come into the world, and men loved the darkness rather than the light; for their deeds were evil. 20 For everyone who does evil hates the light, and does not come to the light, lest his deeds should be exposed. 21 But he who practices the truth comes to the light, that his deeds may be manifested as having been wrought in God.
Men ultimately reject Christ in order to pursue their own course. Ironically, such a purpose is not without its consequences—the consequences of greater and greater degeneration as Paul makes clear in Romans 1:18ff. The consequences here in Revelation 9 are two-fold, though tied together: (a) rampant demonism and (b) gross idolatry. Paul teaches us in 1 Corinthians 10:20 that behind all idolatry is demonism or the worship of demons.
There are basically four levels of demonic activity in the world today:
(2) Demon Subjection or Control: This occurs through the lust patterns of the flesh and the many temptations found in the world which, of course, operates to a large degree under Satan’s control and influence. It is for this reason that he is called “the god of this world” (age) (2 Cor. 4:4) and “the ruler of this world” (John 12:31; 16:11). See also Ephesians 2:2 and 1 John 2:15-17; Mark 4:14-19.
(3) Demon Harassment or Oppression: This involves direct demonic attack that often leads to severe harm mentally, emotionally, and physically. This is possibly the cause of Paul’s thorn in the flesh that he describes as “a messenger of Satan” mentioned in 2 Corinthians 12:7.
(4) Demon Possession: Demon possession is the condition where a demon (or demons) actually take up residence within the body of a person and not only controls the person, but uses their central nervous system and vocal cords. The gospels are filled with illustrations of this.
For more detailed information on this issue, see the bibliography at the end of this lesson.
The idols of gold and silver will probably include the whole gamut of materialism (cf. Eph. 5:5; Col. 3:5), but by this time it will be far beyond this into rank idol worship in the form of worship of the beast (cf. Rev. 13).
The last phrase of verse 21, “which can neither see nor hear nor talk,” is stark irony to bring out the supreme foolishness of all forms of idolatry (see Ps. 115:3-8; Isa. 44:9f). Man’s idols, materialism included, are empty of capacity to meet his needs. Man’s idols are helpless nothings.
Here we have the natural outcome of the preceding two characteristics of man at this time. God is holy, just, love, goodness, mercy and grace, etc. Demons are unholy, unjust, hateful, cruel, murderous, destructive, immoral, etc. When men reject God, the only thing left is the world of Satan. Today Satan’s ministers (servants) often take on the form of goodness, the form of light. But of course, this is only a smoke screen. In the Tribulation, however, the true nature of Satan’s kingdom will surface. In verse 21 John gives us four results that characterize men of Satan’s kingdom and of all men of the Tribulation.
The first sin mentioned is murder. Note that the passage says “murders” (plural). Murder will be rampant. No one will think anything of killing another human being. The ‘law of the jungle’ will prevail. Unfortunately, we can see the nature of this in our own country today since we have left the absolutes of the Word of God. Currently, one of our judges is having to battle to keep a copy of the Ten Commandments on the wall of his court room.
The second sin mentioned is sorcery. This is again plural. The Greek word is farmakon, “a drug, incantation, enchantment.”131 Our word pharmacy comes from this word group. The verb farmakeuw means “to administer drugs.” The word referred to magical arts, but the use of drugs is often a part of witchcraft or demonism. This suggests that drugs will be a big part of the Tribulation. In the Tribulation practically everyone will be on drugs and men will kill and steal to get them.
The third sin mentioned is immorality. This is the Greek word porneia from which we get our word pornography. Porneia looks at sexual sins and perversions of every type.
The fourth sin mentioned is thefts. This is the Greek word klemma, “a thing stolen,” or “theft, stealing.” This too is plural and draws our attention to the complete moral breakdown where men will lie, steal, cheat, and defraud at every turn.
The bonds of society loosened, all mutual respect for each other’s rights, even in the most sacred relationship, completely gone, what follows? Greed will lure on the mass of men “not killed” to enrich themselves at the expense of society. “Each one for himself” is the order and motto of these coming days.132
What a horrible and grim picture the Spirit of God has painted for us of these final days!!! Men will hold nothing sacred anymore. Not life, not marriage or the family or sex, not one’s health, nor the property and rights of others. Man will be given over completely to sensual indulgence and he will do anything to satisfy his cravings. Is not this in itself the greatest judgment he will face? It demonstrates the total ruin of all meaning to life. I used to think this condition in society and the misery of man’s soul at this point would be great beyond imagination. But now in the nineties we see (in our country as well as others) the same signs of moral degeneration—a hardened and unrepentant spirit and moral decadence of the worst kind—murder and violence, stealing in every conceivable form (from petty theft to political and corporate fraud), and gross immorality. It’s a frightening picture.
I am convinced from Scripture that the church will not go into the Tribulation. I believer the Lord’s return for us is imminent and that we do not look for signs of His coming for the church. He could have come in John’s or Paul’s lifetime, and He could come for His bride today.
It would appear, however, that there are certain signs of the approach of the Tribulation in preparation for setting the stage for the events described in Revelation 6-19 and other prophetic passages. Surely we are seeing something of this today and the church could go through a great deal of persecution as the world grows worse and worse. Actually, many believers are undergoing tremendous suffering in various parts of the world already. May we continue to look up and pray, come quickly Lord Jesus.
