Then I saw a door open in Heaven, and a white horse appeared. Its rider was named "Faithful and True" --being One who in righteousness acts as Judge, and makes war. His eyes were like a flame of fire, and on His head were many kingly crowns; and He has a name written upon Him which no one but He Himself knows. The outer garment in which He is clad has been dipped in blood and His name is THE WORD OF GOD. read more.
The armies in Heaven followed Him--mounted on white horses and clothed in fine linen, white and spotless. From His mouth there comes a sharp sword with which He will smite the nations; and He will Himself be their Shepherd, ruling them with a scepter of iron; and it is His work to tread the winepress of the fierce anger of God, the Ruler of all. And on His outer garment and on His thigh He has a name written, KING OF KINGS AND LORD OF LORDS. And I saw a single angel standing in the full light of the sun, who cried in a loud voice to all the birds that flew across the sky, "Come and be present at God's great supper, that you may feast on the flesh of kings and the flesh of generals and the flesh of mighty men, on the flesh of horses and their riders, and on the flesh of all mankind, whether they are free men or slaves, great men or small." And I saw the Wild Beast, and the kings of the earth, and their armies, all assembled to make war, once for all, against the Rider upon the horse and against His army. And the Wild Beast was captured, and with him the false Prophet who had done the miracles in his presence with which he had led astray those who had received the mark of the Wild Beast, and those who worshipped his statue. Both of them were thrown alive into the Lake of fire that was all ablaze with sulphur. But the rest were killed with the sword that came from the mouth of the Rider on the horse. And the birds all fed ravenously upon their flesh.

Revelation 2:12-16

"To the minister of the Church at Pergamum write as follows: "'This is what He who has the sharp, two-edged sword says. I know where you dwell. Satan's throne is there; and yet you are true to Me, and did not deny your faith in Me, even in the days of Antipas My witness and faithful friend, who was put to death among you, in the place where Satan dwells. Yet I have a few things against you, because you have with you some that cling to the teaching of Balaam, who taught Balak to put a stumbling-block in the way of the descendants of Israel--to eat what had been sacrificed to idols, and commit fornication. read more.
So even you have some that cling in the same way to the teaching of the Nicolaitans. Repent, at once; or else I will come to you quickly, and will make war upon them with the sword which is in My mouth.

Isaiah 49:1-2

Hosea 6:1-5

Revelation 1:14-17

His head and His hair were white, like white wool--as white as snow; and His eyes resembled a flame of fire. His feet were like silver-bronze, when it is white-hot in a furnace; and His voice resembled the sound of many waters. In His right hand He held seven stars, and a sharp, two-edged sword was seen coming from His mouth; and His glance resembled the sun when it is shining with its full strength. read more.
When I saw Him, I fell at His feet as if I were dead. But He laid His right hand upon me and said, "Do not be afraid: I am the First and the Last, and the ever-living One.
