blood: There went forth vengeance, even to the rulers of the people. For in the last contest there went forth vengeance even to the devil and his angels, because of the blood of the saints which was shed; as it is written, "In blood thou hast sinned, and blood pursueth thee." Concerning the horses, it has been spoken above.
