In this case it’s probably from Revelation:
And I saw when the Lamb opened one of the seals, and I heard, as it were the noise of thunder, one of the four beasts saying, Come and see. And I saw, and behold a white horse: and he that sat on him had a bow; and a crown was given unto him: and he went forth conquering, and to conquer. And when he had opened the second seal, I heard the second beast say, Come and see. And there went out another horse that was red: and power was given to him that sat thereon to take peace from the earth, and that they should kill one another: and there was given unto him a great sword.

I enjoyed the series and really raced through them - they're good pageturners. The first volume is pretty much the Chu-Han Contention with names changed, but events and characters diverge from there. (There's another continent, with "floating cities" that attack the continent in the first book.) Although sometimes the technological developments the characters come up with are a little too timely and convenient, I thought it was a much more interesting approach than giving them magical powers. The main supernatural element is the presence of the gods, who mess with things in the manner of amused spectators.
Definitely a good pick if you're interested in a fantasyish series that's not Western-coded.
