And I saw Heaven opened, and behold, a white horse; and he that sat upon him is called faithful and true, and in righteousness he does judge and make war; his eyes were as a flame of fire. And he had on his head many crowns, and a name written that no man knew but himself. And he is clothed with a vesture dipped in blood. And his name is called The Word of God. And the armies which were in Heaven followed him upon white horses, clothed in fine linen, white and clean. And out of his mouth proceeds the word of God, and with it he will smite the nations, and he will rule them with the word of his mouth. And he treads the winepress in the fierceness and wrath of Almighty God. And he has on a vesture, and on his thigh a name written: King of kings, and Lord of lords.
Revelation 8:1

For behold, the Lord will come with fire and with his chariots like a whirlwind, to render his anger with fury and his rebuke with flames of fire. For by fire and by his sword will the Lord plead with all flesh, and the slain of the Lord shall be many.
Isaiah 25:2
