Revelation 19:11, 14-15

Then I saw heaven opened, and a white horse was standing there. Its rider was named Faithful and True, for he judges fairly and wages a righteous war.

The armies of heaven, dressed in the finest of pure white linen, followed him on white horses. From his mouth came a sharp sword to strike down the nations. He will rule them with an iron rod. He will release the fierce wrath of God, the Almighty, like juice flowing from a winepress.
