Zechariah 1:8

I saw by night, in a night vision, some time between six o'clock in the evening and six o'clock in the morning, and behold a man riding upon a red horse, the color of war and bloodshed, and he stood among the myrtle trees that were in the bottom, most likely a valley in the neighborhood of Jerusalem; and behind him were there red horses, speckled, or bay, the color of fire and flames and burning, and white, in this connection the color of victory.
