Revelation 16:12-14
The individual units within this chapter are fairly easy to delineate due to the series of seven angels with their bowls of wrath. And there is a verbal similarity between the first and last of these bowls in that both contain the words “a loud voice from the temple,” “earth,” and “his (God's) wrath.” In addition, the two longest sections, those devoted to the third and sixth angels, appear to have similar internal organizations, as shown below:
Third angel (vv. 4-5a)
1. Words of the angel (vv. 5b-6)
2. Response to the angel (v. 7)
Sixth angel (vv. 12-14)
1. Words of Christ (v. 15)
2. Response of the kings (v. 16)
Note the other similarities between these two units. They are the only ones of the seven in the chapter to contain the word “river(s).” The first of these two sections ends as does the beginning of the second, with the only occurrences of “God the Almighty” in the chapter.
Also, the third angel's section is unified by the repeated words “blood” (vv. 4,6a,b) as well as “You are just, O Holy One / O Lord (v. 3)...your judgments are true and just (v. 7).”
With that in mind, look next at the repeated language in the section concerning the sixth angel: “assemble” (vv. 14,16) and “kings from the east” (12) / “kings of the whole world” (v. 14).
Since the repeated words in vv. 4-7 are all used with the same referents, one may rightly suppose that the “assembling” in verses 14 and 16 refers to the same event. But is the same true of the the kings mentioned in verses 12 and 14? That is the question I was curious to explore. However, trying to find any sort of consensus among commentators on this subject proved to be futile. As Walvoord explains, “There has been endless speculation about 'the kings from the East.' with many expositors trying to relate them to some contemporary leaders of their generation. A survey of 100 commentators of the Book of Revelation reveals at least 50 interpretations of the identity of the kings of the East.”
And this whole issue is somewhat bound up with endless geographical, historical, and Old Testament prophetic issues which together impact on our understanding. So the best I can hope to do is to simply present a range of opinions, presented roughly in order, beginning with the strictly literal and ending with the highly symbolic.
Phillips says that “the revived Roman Empire commanded by the beast...is now in turmoil, and his power in the east has dried up, making it possible for China, India, Japan and other eastern powers to unite...The way of the kings of the east is prepared, and at long last the awakened millions of Asia see their way clear to avenge themselves on the hated powers of the west.” Similarly, he feels that demons will rile up the other nations, all against God.
Walvoord: “The simplest and best explanation, however, is that this refers to kings or rulers from the Orient or East who will participate in the final world war...In the light of the context of this passage indicating the near approach of the second coming of Christ and the contemporary [written in 1983] world situation in which the Orient today contains a large portion of the world's population with tremendous military potential, any interpretation other than a literal one does not make sense.”
Beale critiques this literal understanding: “In the OT God is always the one who dries up the water, whether for redemption or judgment. Therefore, the final defeat of the wicked forces (16:14,16) stands no less under divine direction (not permission) than do their prior attempts to destroy God's people. John understands this pattern typologically and universalizes it. Babylon now represents the world system (as in Jewish writings generally)...And just as Babylon has become universalized and become symbolic..., so the Euphrates cannot be a literal geographical reference to the Euphrates in modern Iraq, Syria, and Turkey but must be figurative and universal...the acknowledgment by some futurist commentators that Babylon symbolizes latter-day Rome is inconsistent with their typical literalist approach to the beast and to this very passage, where they understand the Euphrrates and the kings from the east to be literal...In fact, 'the kings of the east' may be synonymous with 'the kings of the whole inhabited earth.' The universal effect is also apparent from 13:13 and 19:19-20, where both 'kings of the earth' and idolatrous 'inhabitants of the earth' are deceived.”
Beale and McDonough: “The OT prophesies that this judgment [against Babylon] would include the drying up of the Euphrates River (Isa.11:15; 44:27; Jer. 50:38; 51:36; cf. Zech.10:11). The prophecy was fulfilled by Cyrus who diverted the waters of the Euphrates (cf. Isa. 44:27-28)...Against this back- ground, it can be seen that the Battle in Revelation will end in the absolute destruction of all the opponents of God...The nations are deceived to think that they are gathered together to exterminate the saints, but they are gathered together ultimately by God in order to meet their own judgment at the hands of Jesus (19:11-12).”
I heard a recent sermon in which the pastor expressed the belief that the kings of the East must represent the forces of God's people since in the OT God's drying up of the waters always occurred in order to aid them in some way. However, as Beale says above, that sort of miraculous action on His part can stand for judgment as well as redemption. The same was true in the crossing of the Red Sea by the fleeing Israelites, an action which not only redeemed them from captivity but also brought judgment down on Pharaoh and his army.
Bruce: After the blowing of the sixth trumpet four demon-angels bound at the Euphrates frontier were released to invade the Roman Empire. Now, across the dry bed of the river, the kings from the East (a reference to the Parthians and their allies) may invade the Roman provinces unimpeded.”
That same idea is echoed by other commentators. Thus, the footnote in the Jerusalem Bible says, “Kings of the East were the Parthian kings, dreaded by the Roman world.” And Ruiz states that these kings are “probably a reference to the Parthians who would be led by Nero, restored to life.”
But for a different understanding, Beagley says,”When the sixth angel pours his bowl on the river Euphrates, its waters dry up (Rev 16:12), thus eliminating the barrier that afforded protection to Israel from invasion by the enemies to the north.”
And Hendricksen has an even different slant on the identity and target of these Eastern forces: “John sees that the sixth bowl is emptied upon the Euphrates River. This river represents Assyria, Babylonia, the wicked world.When the river is said to dry up, the road is prepared so that all the antichristian powers can make the attack against the church.”
But Beagley feels that Armageddon is “probably a reference to Jerusalem; (Rev 16:12-16).”
Beasley-Murray notes that the kings of the east “are further described in 17:12,13; they put themselves at antichrist's behest (17:17), ravaging the harlot city and war with the Lamb (17:14).”
Payne sees parallel accounts in Rev 9:13-21 and 16:12-14,16 with the large army of horsemen in 9:16 corresponding to the frogs in 16:13-14.These “suggest demonic legions” whose purpose is to gather the kings of the world together for war (v. 14). He then states that it was to this same end that the 6th angel had dried up the Euphrates in v. 12. But he never equates the two armies of kings or tries to show the correspondence between the two, if there is one.
“Just as the OT is at variance with oriental views of divine kingship, so the NT is opposed to Hellenistic and Roman ideas of this kind: the earthly king is not an incarnation of the deity, since no one but God or the Messiah can occupy such a position...The OT attitude to the great kings is found again in the NT with regard to the 'kings of the east' (Rev. 16:12): the supremacy of God is asserted by making them a rod in his hand, only to destroy them at the last day if they do not submit to him in obedience (Rev 17:2ff.; 18:3ff.' 19:18ff.; 21:24).” (Klappert)
But the question still remains – Are they a willing, unwilling, or unwitting rod? The final reference to kings in the Bible is found in Revelation 21:24 where the kings of the earth will willingly bring their splendor into the heavenly Jerusalem. However in the New Testament, “human kings are usually seen as setting themselves against Yahweh and his anointed one...Such kings are known as...'kings of the whole world' (Rev 16:14).” (Dictionary of Biblical Imagery)
Then Morris points out an interesting phenomenon: “By appealing to contemporary fears [concerning the Parthians] he [John] is making the point that at the end of time the divided forces of evil will engage in a terrible conflict. Curiously, having told us that the way will be cleared for mighty potentates to march westward John does not follow up the thought. He does not speak of the kings [of the East] as using the way prepared tor them. In fact he does not mention them again.”
Ford first reviews what others have to say about the sixth bowl: “Allo and others think the effect of this sixth bowl represents the various forces that cause the social and political machinery of the [Roman] Empire to crumble and thus render it defenseless before the barbarian invasion. Cambier adopts an eschatological interpretation; he sees the demons gathering 'the kings of the universe' for the battle with the Lord (vs. 14) as symbolic of the end of the world.”
Next Ford expresses her personal view. And since she feels much of Revelation was written by John the Baptist, it is understandable that her opinion is that the judgments of the bowls are against unbelieving Israel. Thus, “the irony of the sixth bowl lies in the fact that on at least two occasions waters 'stood still' so that the Israelites could pass over safely...All these incidents profit Israel and bring disaster to their enemies, but the author of Revelation predicts the exact opposite. The Euphrates is dried up so that the way will be clear for an invasion from the east.”
Mounce has the most to say on this subject among the commentaries I consulted. Here are just a few of his comments:
First, he states, “The Euphrates marked the eastern boundary of the land given by covenant to Abraham and his seed (Gen 15:18; Deut 1:7-8; Josh 1:3-4). It also separated the Roman Empire on the east from the much feared Parthians. Then he echoes some of the above scholars in feeling that there is irony in this passage in that this drying up of the river will actually aid the enemy, concluding: Whatever the ultimate reference the historical context of John's imagery favors the interpretation of the kings as Parthian rulers.” And if so, then that would fit in with the legend that a revived Nero would command their troops in attacking Rome. However, “some confusion results from the fact that this tradition is partially intertwined in Revelation with an older tradition that portrays a final assault on the people of God by the united kings of earth (Joel 3:2; Zeph 3:8). The kings of the East (vs. 12) who will lay siege to Rome (17:15-18 and chap. 18) are distinct from the kings of the whole world (vs. 14) who will wage the final war against Christ and the armies of heaven (19:11-21...)...The closest literary parallel is Isaiah 11:15-16, where the River (Euphrates) is smitten into seven channels so men may cross dryshod and a highway leads from Assyria to Israel for the returning remnant (cf. Jer 51:36; Zech 10:11; II Esdr 13:47).”
Conclusion
As you can see, there are so many possibilities given here based on numerous parallels in the Bible as well as historical sources that anyone who claims to have the authoritative last word on the subject should be listened to with great suspicion. And that comment applies, to a somewhat lesser extent, to the rest of the book of Revelation as well. The safest course is probably to glean from the book possible life application lessons for ourselves (and there are such to be found) and leave the exact details of future events firmly in God's hands.
