And I saw heaven opened - He saw a new vision, as if an opening were made through the sky, and he was permitted to look into heaven. See the notes on Revelation 4:1.
And behold, a white horse - On the white horse as a symbol, see the notes on Revelation 6:2. He is here the symbol of the final victory that is to be obtained over the beast and the false prophet Revelation 19:20, and of the final triumph of the church.
And he that sat upon him was called Faithful and True - He is not designated here by his usual and real name, but by his attributes. There can be no doubt that the Messiah is intended, as he goes forth to the subjugation of the world to himself. The attributes here referred to - faithful and true - are especially appropriate, for they are not only strongly marked attributes of his character, but they would be particularly manifested in the events that are described. He would thus show that he was faithful - or worthy of the confidence of his church in delivering it from all its enemies; and true to all the promises that he has made to it.
And in righteousness he doth judge - All his acts of judgment in determining the destiny of people are righteous. See the notes on Isaiah 11:3-5.
And make war - That is, the war which he wages is not a war of ambition; it is not for the mere purpose of conquest; it is to save the righteous, and to punish the wicked.

A white horse - This is an exhibition of the triumph of Christ after the destruction of his enemies. The white horse is the emblem of this, and Faithful and True are characters of Christ. See Revelation 3:14.
In righteousness he doth judge and make war - The wars which he wages are from no principle of ambition, lust of power, or extension of conquest and dominion; they are righteous in their principle and in their object. And this is perhaps what no earthly potentate could ever say.

(12) And I saw (13) heaven opened, and behold a white horse; and he that sat upon him [was] called Faithful and True, and in righteousness he doth judge and make war.
(12) The second part of this chapter (as I said in) See Revelation 19:1 is of the victory gained by Christ against both the beasts: in which first Christ is described as one ready to fight, to the sixteenth verse (Revelation 19:12-16), then the battle is shown to begin, there to the eighteenth verse (Revelation 19:17-18), lastly is set forth the victory, to the end the chapter (Revelation 19:19-21). In this place the most excellent properties of Christ as our heavenly judge and avenger shine forth, according to his person, company, effects and names.
(13) Properties belonging to his person, that he is heavenly, judge, faithful, true, just, in this verse, knowing all things, ruling over all, to be known by no one, (Revelation 19:12), the triumpher and in essence, the Word of God, in (Revelation 19:13).

And I saw heaven opened,.... This vision refers not to the same time the first seal does, Revelation 6:2 for though a white horse, with a rider on it, is seen here, as there; that respects the first times of the Gospel, this the latter part of the dispensation of it; nor to the war in heaven between Michael and the dragon, and their angels, Revelation 12:7 that issued in the downfall of Paganism in the Roman empire, this will issue in the downfall of the Papacy in it; nor to the personal coming of Christ to the last judgment, of which an account is given in the following chapter; but to the battle at Armageddon, to which the sixth vial is a preparation, and which is finished under the seventh, Revelation 16:13 and what is briefly hinted at there is at large related here; in which Christ, the General, and his armies, on the one hand, and the kings of the earth, with the beast and false prophet, and their armies, on the other hand, appear to give battle to each other: and the issue of the battle is particularly represented, in order to have a view of which, "John saw heaven opened": not literally, as at Christ's baptism, and at the stoning of Stephen, nor in a spiritual sense, by the blood of Christ, but visionally, as in Revelation 4:1 and since heaven, often in this book, signifies the church on earth, a more glorious and comfortable state of the church may be designed; when her gates shall be opened continually, and not shut day nor night, to receive the forces of the Gentiles, and their kings, Isaiah 60:15 such a state as is referred to in Revelation 11:19 to which visions this is contemporary; and it may denote a very glorious appearing of Christ, not in person, which will be after this, but in his kingdom and power, in defeating his enemies, and reigning spiritually with his saints: and it may also design the clear revelation and discerning John had of the following things:
and behold a white horse which, as in Revelation 6:2 may be a symbol of the Gospel, and Gospel ministers, as there in the former, here in the latter part of the Gospel dispensation; signified by a horse, to denote the swift progress of the Gospel in the latter day, the majesty, power, and authority with which it will come, bearing down all opposition made against it; and by a white horse, to express the purity of the Gospel, and of its preachers and professors, and the peace it publishes, and gives, and the joy it brings, and the triumphs that will attend it.
And he that sat upon him was called Faithful and True: that Christ is here meant, is evident from the description of his eyes, Revelation 19:12 being the same as in Revelation 1:14 and from his name, Revelation 19:13 which is the peculiar name of the Son of God, John 1:1 and he sits upon, and is bore by, and rides forth in the Gospel, and the ministry of it, with glory and majesty, and prosperously, Psalm 45:3 and the characters of faithful and true well agree with him; See Gill on Revelation 3:7. See Gill on Revelation 3:14. He is "faithful and true" to God, who appointed him a Leader and Commander of the people, and to them he is the Commander of: and these characters well suit him now, when he will accomplish all the glorious things spoken of the church, relating to her spiritual and happy state in the latter day, and serve greatly to recommend him as a General.
And in righteousness he doth judge and make war; which is to be understood not of the last judgment, though that will be executed in righteousness, and therefore is called the righteous judgment, yet in that day there will be no war, no opposition, the wicked will at once submit; but of Christ's judging of his people, and avenging their blood on their enemies, and the remainder of them among Papists, Pagans, and Mahometans; who will be gathered together at Armageddon in battle array against them, when there will be an utter discomfiture of them in righteous judgment; for as in times past the beast made war with the saints and witnesses, and overcame them, Christ will enable his people to make war with him and his accomplices, and overcome them, as the sequel of this vision shows, Christ being at the head of them, though not in person, yet in power.

Christ, the glorious Head of the church, is described as on a white horse, the emblem of justice and holiness. He has many crowns, for he is King of kings, and Lord of lords. He is arrayed in a vesture dipped in his own blood, by which he purchased his power as Mediator; and in the blood of his enemies, over whom he always prevails. His name is "The Word of God;" a name none fully knows but himself; only this we know, that this Word was God manifest in the flesh; but his perfections cannot be fully understood by any creature. Angels and saints follow, and are like Christ in their armour of purity and righteousness. The threatenings of the written word he is going to execute on his enemies. The ensigns of his authority are his name; asserting his authority and power, warning the most powerful princes to submit, or they must fall before him. The powers of earth and hell make their utmost effort. These verses declare important events, foretold by the prophets. These persons were not excused because they did what their leaders bade them. How vain will be the plea of many sinners at the great day! We followed our guides; we did as we saw others do! God has given a rule to walk by, in his word; neither the example of the most, nor of the chief, must influence us contrary thereto: if we do as the most do, we must go where the most go, even into the burning lake.

behold a white horse; and he that sat upon him--identical with Revelation 6:2. Here as there he comes forth "conquering and to conquer." Compare the ass-colt on which He rode into Jerusalem (Matthew 21:1-7). The horse was used for war: and here He is going forth to war with the beast. The ass is for peace. His riding on it into Jerusalem is an earnest of His reign in Jerusalem over the earth, as the Prince of peace, after all hostile powers have been overthrown. When the security of the world power, and the distress of the people of God, have reached the highest point, the Lord Jesus shall appear visibly from heaven to put an end to the whole course of the world, and establish His kingdom of glory. He comes to judge with vengeance the world power, and to bring to the Church redemption, transfiguration, and power over the world. Distinguish between this coming (Matthew 24:27, Matthew 24:29, Matthew 24:37, Matthew 24:39; Greek, "parousia") and the end, or final judgment (Matthew 25:31; 1-Corinthians 15:23). Powerful natural phenomena shall accompany His advent [AUBERLEN].

And I saw the heaven opened. This implies the opening of a new vision. See Revelation 4:1; Revelation 11:19. Where a former vision is continued the formula is "After these things." We now have a series of pictures symbolizing the closing events that inaugurate the Millennium. The first of these is the one before symbolized by the angel that flies through heaven with the everlasting gospel, but now presented in a grand vision of the triumphant march of the Word of God.
Behold a white horse. Always the symbol of conquest and triumph. See notes on Revelation 6:2.
He that sat upon him called Faithful and True. It is the Lord, who comes as the Word of God. His conquests are effected by the word, but the march is really the march of Christ.
His eyes were as a flame of fire. See note on Revelation 1:14.
Upon his head were many crowns. Diadems. All kingly authority is concentrated in his hands. He is King of kings.
A name written that no man knew. Probably the new name of Revelation 2:17, a name which will be disclosed to those invited to the marriage supper of the Lamb (Revelation 3:12).
He is arrayed in a garment sprinkled with. See Revision. The word in the best Greek MSS. is not Bebammemnon ("dipped"), but "sprinkled." The usual idea is that the sprinkled blood is that of his conquered enemies. I believe that the thought is the sprinkling of his own blood, the blood through which he conquers.
And the armies which were in heaven followed him. These armies are the armies of the saints, purified, holy, a conquering host, led by Christ to victory.
Out of his mouth goeth a sharp sword. See note on Revelation 1:16. This symbolizes the word by which he achieved his conquests.
He shall rule them with a rod of iron. See notes on Revelation 2:27 and Revelation 12:5. This implies not a stern, but a firm and lasting rule.
He treadeth the winepress. He shall inflict God's judgments on the sins of the earth. See notes on Revelation 14:17-19.
He hath on his vesture and on his thigh. This probably signifies that the name was written on his vesture, even on his thigh. The Greek may be so translated.
King of Kings. Of the various titles given to Christ in this passage this is the highest and marks him as supreme. There are four titles given in the passage: (1) in Revelation 19:11; (2) Revelation 19:12; (3) Revelation 19:13, and (4) in Revelation 19:16.

And I saw the heaven opened - This is a new and peculiar opening of it, in order to show the magnificent expedition of Christ and his attendants, against his great adversary. And behold a white horse - Many little regarded Christ, when he came meek, "riding upon an ass;" but what will they say, when he goes forth upon his white horse, with the sword of his mouth? White - Such as generals use in solemn triumph. And he that sitteth on him, called Faithful - In performing all his promises. And True - In executing all his threatenings. And in righteousness - With the utmost justice. He judgeth and maketh war - Often the sentence and execution go together.
