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. Another horse - red - The emblem of war; perhaps also of severe persecution, and the martyrdom of the saints.
Him that sat thereon - Same say, Christ; others, Vespasian; others, the Roman armies; others, Artabanus, king of the Parthians, etc., etc.
Take peace from the earth - To deprive Judea of all tranquillity.
They should kill one another - This was literally the case with the Jews, while besieged by the Romans.
A great sword - Great influence and success, producing terrible carnage.
