What does Revelation 9:17 Mean?

Verse Meaning

Now John saw what these horsemen looked like. Horses were swift implements of war in ancient times. Red, blue, and yellow breastplates covered both horses and riders. This was apparently their only armor, and it is defensive armor. Hyacinth is a flower that is most commonly blue, and brimstone is sulfur that is yellow. Lion-like horse heads could be very different from those of ordinary horses or just heads of horses that appear exceptionally bold and majestic. Lions are terrifying (cf. Revelation 10:3), fierce (cf. Revelation 9:8), and destructive (cf. Revelation 13:2). Natural horses do not breath fire, smoke, and brimstone. These may be figures describing their prophecies of judgment (cf. Revelation 11:5-6). This verse suggests that this army is probably something other than a human army of cavalry, probably an angelic army (cf. Revelation 9:9). However some interpreters, both premillennial and amillennial, have believed that this will be a human army. [1]

Context Summary

Revelation 9:12-21 - Impenitent In Spite Of All
The river Euphrates possibly stands for nations and hordes of men emanating from that region; and these verses are held by a large number of expositors to foretell the invasion of Europe by the Turks, who have desolated and held the sacred places of the Jewish faith. The Church of that time was eaten through with idolatry. Image worship had become almost universal, and the invariable consequence of this relapse from the noble spiritual ideals of the Jewish and Christian dispensations was materialism, sensuality, and the greed of the priest. On the other hand, the Turks were fierce iconoclasts, and their progress everywhere was marked by the demolition of Christian emblems.
Demons contrive to get themselves worshiped under the effigies of idolatry; and murders, sorceries, fornication, and theft infest their temples. There is perpetual controversy between the spirit of truth and these perversities; and this conflict must continue, not only in the Church, but in the heart, until everything that opposes the reign of the Spirit is overthrown, and every thought is brought into captivity to the obedience of Christ, 2 Corinthians 10:5. Is this supremacy of the Spirit secured for thee, my reader? [source]

Of jacinth [ὑακινθίνους]
Ὑάκινθος hyacinthis the name of a flower and also of a precious stone. The noun occurs only Revelation 21:20, and the adjective only here. According to classical mythology, the flower sprang up from the blood of Hyacinthus, a beautiful Spartan youth, who was accidentally killed during a game of quoits. It was thought by some that the letters AI, AI, the exclamation of woe, could be traced on the petals, while others discovered the letter Υ ,the initial letter of Ὑάκινθος .

Perhaps light yellow, such a color as would be produced by the settling fumes of brimstone. [source]
Of the horses []
In the Bible the horse is always referred to in connection with war, except Isaiah 28:28, where it is mentioned as employed in threshing, the horses being turned loose in the grain as in the Italian triglia. The magnificent description in Job 39:19-25applies to the war-horse. He is distinguished not so much for his speed and utility as for his strength (see Psalm 33:17; Psalm 147:10), and the word abbir strong is used as an equivalent for a horse (Jeremiah 8:16; Jeremiah 47:3). The Hebrews as a pastoral race, did not need the horse; and, for a long time after their settlement in Canaan, dispensed with it, partly because of the hilly nature of the country, which allowed the use of chariots only in certain places (Judges 1:19), and partly because of the prohibition in Deuteronomy 17:16. Accordingly they hamstrung the horses of the Canaanites (Joshua 11:6, Joshua 11:9). The great supply of horses was effected by Solomon through his connection with Egypt. See 1 Kings 4:26. [source]

Acts 2:17 I will pour forth [εκχεω]
Future active indicative of εκχεω — ekcheō This future like εδομαι — edomai and πιομαι — piomai is without tense sign, probably like the present in the futuristic sense (Robertson, Grammar, p. 354). Westcott and Hort put a different accent on the future, but the old Greek had no accent. The old Greek had εκχευσω — ekcheusō This verb means to pour out. Of my Spirit (απο του πνευματος — apo tou pneumatos). This use of απο — apo (of) is either because of the variety in the manifestations of the Spirit (1 Corinthians 12) or because the Spirit in his entirety remains with God (Holtzmann, Wendt). But the Hebrew has it: “I will pour out my Spirit” without the partitive idea in the lxx. And your daughters Anna is called a prophetess in Luke 2:36 and the daughters of Philip prophesy (Acts 21:9) and Acts 2:18 (handmaidens). See also 1 Corinthians 11:5 Visions (ορασεις — horaseis). Late word for the more common οραμα — horama both from οραω — horaō to see. In Revelation 4:3 it means appearance, but in Revelation 9:17 as here an ecstatic revelation or vision. Dream dreams Shall dream with (instrumental case) dreams. First future passive of ενυπνιαζω — enupniaz from ενυπνιος — enupnios Intensive particle γε — ge added to και — kai (and), an emphatic addition (=Hebrew vegam). Servants Slaves, actual slaves of men. The humblest classes will receive the Spirit of God (cf. 1 Corinthians 1:26-31). But the word “prophesy” here is not in the lxx (or the Hebrew). [source]

Revelation 14:10 Of the wine of the wrath of God [εκ του οινου του τυμου του τεου]
Note εκ — ek (partitive) after πιεται — pietai In Revelation 16:19; Revelation 19:15 we have both τυμου — thumou and οργης — orgēs (wrath of the anger of God). The white heat of God‘s anger, held back through the ages, will be turned loose.Prepared unmixed (του κεκερασμενου ακρατου — tou kekerasmenou akratou). A bold and powerful oxymoron, “the mixed unmixed.” Ακρατος — Akratos is an old adjective (alpha privative and κεραννυμι — kerannumi to mix) used of wine unmixed with water (usually so mixed), here only in N.T. So it is strong wine mixed (perfect passive participle of κεραννυμι — kerannumi) with spices to make it still stronger (cf. Psalm 75:9).In the cup of his anger Both τυμος — thumos (vehement fury) and οργη — orgē (settled indignation).He shall be tormented (βασανιστησεται — basanisthēsetai). Future passive of βασανιζω — basanizō See Revelation 9:5; Revelation 11:10.With fire and brimstone See Revelation 9:17 for fire and brimstone and also Revelation 19:20; Revelation 20:10; Revelation 21:8.

Revelation 16:13 Three unclean spirits [πνευματα τρια ακαταρτα]
Out of the mouths of each of the three evil powers (the dragon and the two beasts) comes an evil spirit. See the use of mouth in Revelation 1:16 (Revelation 9:17.; Revelation 11:5; Revelation 12:15; Revelation 19:15, Revelation 19:21) as a chief seat of influence. In 2 Thessalonians 2:8 we have “the breath of his mouth” (the other sense of πνευμα — pneuma). For ακαταρτον — akatharton (unclean) with πνευμα — pneuma see Mark 1:23.; Mark 3:11; Mark 5:2.; Acts 5:16; Acts 8:7. Christ expelled unclean spirits, but His enemies send them forth” (Swete).

[source]
Revelation 1:1 The Revelation [ἀποκάλυψις]
The Greek word is transcribed in Apocalypse. The word occurs only once in the Gospels, Luke 2:32, where to lighten should be rendered for revelation. It is used there of our Lord, as a light to dispel the darkness under which the heathen were veiled. It occurs thirteen times in Paul's writings, and three times in first Peter. It is used in the following senses: (a.) The unveiling of something hidden, which gives light and knowledge to those who behold it. See Luke 2:32(above). Christianity itself is the revelation of a mystery (Romans 16:25). The participation of the Gentiles in the privileges of the new covenant was made known by revelation (Ephesians 3:3). Paul received the Gospel which he preached by revelation (Galatians 1:12), and went up to Jerusalem by revelation (Galatians 2:2). -DIVIDER-
-DIVIDER-
(b.) Christian insight into spiritual truth. Paul asks for Christians the spirit of revelation (Ephesians 1:17). Peculiar manifestations of the general gift of revelation are given in Christian assemblies (1 Corinthians 14:6, 1 Corinthians 14:26). Special revelations are granted to Paul (2 Corinthians 12:1, 2 Corinthians 12:7). -DIVIDER-
-DIVIDER-
(c.) The second coming of the Lord (1 Peter 1:7, 1 Peter 1:13; 2 Thessalonians 1:7; 1 Corinthians 1:7) in which His glory shall be revealed (1 Peter 4:13), His righteous judgment made known (Romans 2:5), and His children revealed in full majesty (Romans 8:19). -DIVIDER-

The word is compounded with ἀπό fromand καλύπτω tocover. Hence, to remove the cover from anything; to unveil. So of Balaam, the Lord opened or unveiled his eyes ( ἀπεκάλυψεν τοὺς ὀφθαλμοὺς : Numbers 22:31, Sept.). So Boaz to Naomi's kinsman: “I thought to advertise thee:” Rev., “disclose it unto thee” ( ἀποκαλύψω τὸ οὖς σου : Rth 4:4 , Sept.). Lit., I will uncover thine ear. -DIVIDER-
-DIVIDER-
The noun ἀποκάλυψις revelationoccurs only once in the Septuagint (1 Samuel 20:30), in the physical sense of uncovering. The verb is found in the Septuagint in Daniel 2:19, Daniel 2:22, Daniel 2:28. -DIVIDER-
-DIVIDER-
In classical Greek, the verb is used by Herodotus (i., 119) of uncovering the head; and by Plato: thus, “reveal ( ἀποκαλύψας ) to me the power of Rhetoric” (“Gorgias,” 460): “Uncover your chest and back” (“Protagoras,” 352). Both the verb and the noun occur in Plutarch; the latter of uncovering the body, of waters, and of an error. The religious sense, however, is unknown to heathenism. -DIVIDER-

The following words should be compared with this: Ὀπτασία avision (Luke 1:22; Acts 26:19; 2 Corinthians 12:1). Ὅραμα avision (Matthew 17:9; Acts 9:10; Acts 16:9). Ὅρασις avision (Acts 2:17; Revelation 9:17. Of visible form, Revelation 4:3). These three cannot be accurately distinguished. They all denote the thing seen or shown, without anything to show whether it is understood or not. -DIVIDER-

As distinguished from these, ἀποκάλυψις includes, along with the thing shown or seen, its interpretation or unveiling. -DIVIDER-
-DIVIDER-
Ἐπιφάνεια appearing(hence our epiphany ), is used in profane Greek of the appearance of a higher power in order to aid men. In the New Testament by Paul only, and always of the second appearing of Christ in glory, except in 2 Timothy 1:10, where it signifies His first appearing in the flesh. See 2 Thessalonians 2:8; 1 Timothy 6:14; Titus 2:13. As distinguished from this, ἀπολάλυψις is the more comprehensive word. An apocalypse may include several ἐπιφάνειαι appearingsThe appearings are the media of the revealings. -DIVIDER-
-DIVIDER-
Φανέρωσις manifestationonly twice in the New Testament; 1 Corinthians 12:7; 2 Corinthians 4:2. The kindred verb φανερόω tomake manifest, is of frequent occurrence. See on John 21:1. It is not easy, if possible, to show that this word has a less dignified sense than ἀποκάλυψις . The verb φανερόω is used of both the first and the second appearing of our Lord (1 Timothy 3:16; 1 John 1:2; 1 Peter 1:20; Colossians 3:4; 1 Peter 5:4). See also John 2:11; John 21:1. -DIVIDER-
-DIVIDER-
Some distinguish between φανέρωσις as an external manifestation, to the senses, but single and isolated; while ἀποκάλυψις is an inward and abiding disclosure. According to these, the Apocalypse or unveiling, precedes and produces the φανέρωσις or manifestation. The Apocalypse contemplates the thing revealed; the manifestation, the persons to whom it is revealed. -DIVIDER-

Compare “I will give him to sit” (Revelation 3:21): “It was given to hurt” (Revelation 7:2): “It was given him to do;” (A.V. “had power to do;” Revelation 13:14).Servants ( δούλοις )Properly, bond-servants. See on Matthew 20:26; see on Mark 9:35.Must ( δεῖ )As the decree of the absolute and infallible God.Shortly come to pass ( γενέσθαι ἐν τάχει )For the phrase ἐν τάχει shortlysee Luke 18:8, where yet long delay is implied. Expressions like this must be understood, not according to human measurement of time, but rather as in 2 Peter 3:8. The idea is, before long, as time is computed by God. The aorist infinitive γενέσθαι is not begin to come to pass, but denotes a complete fulfilment: must shortly come to pass in their entirety. He sent ( ἀποστείλας )See on Matthew 10:2, Matthew 10:16.Signified ( ἐσήμανεν )From σῆμα asign. Hence, literally, give a sign or token. The verb occurs outside of John's writings only in Acts 11:28; Acts 25:27. See John 12:33; John 18:32; John 21:19. This is its only occurrence in Revelation. The word is appropriate to the symbolic character of the revelation, and so in John 12:33, where Christ predicts the mode of His death in a figure. Compare sign, Revelation 12:1.Angel ( ἀγγέλου )Strictly, a messenger. See Matthew 11:10; Luke 8:24; Luke 9:52.

( Exodus 28:17 ), a golden-greenish stolle; chrysoprase (chrusoprasos), here only in N.T. (not in lxx), in colour like a teek, translucent golden-green; jacinth ( υακιντος — huakinthos ), of the colour of the hyacinth, a violet colour (Pliny), already in Revelation 9:17 like blue smoke, like achates in lxx; amethyst ( αμετυστος — amethustos ), only here in N.T. ( Exodus 28:19 ), of a violet and purple colour, more brilliant than the υακιντος — huakinthos Swete sums up the colours thus: blue (sapphire, jacinth, amethyst), green (jasper, chalcedony, emerald, beryl, topaz, chrysoprase), red (sardonyx, sardius), yellow (chrysolite). But even so there is great variety in hue and brilliancy and in the reaction on each other. Clement of Alexandria argues that this variety illustrates the variety of gifts and graces in the twelve apostles. Possibly so. [source]
