kings: As there are holy kings to whom, when the Euphrates is dried, the way of the East is laid open; so also are there said to be evil kings of the earth, who, without being gathered together from the whole world into one place, but each nation in its place, are to fight against the saints. By "the great day of the Lord," he means the whole time from the Lord's Passion. "The day" may also be taken to be the day of judgment, when the army of the devil, which has been gathered together through the whole time of the present life, will meet the Lord, the King, that it may be overthrown. <a
demons: For as was done by the magicians of Pharaoh, so is it to be supposed that these will perform signs. And not without reason did he remember these, when he had made mention of frogs, but that he might announce that the ministers of Satan would then also perform similar signs. For the magicians were permitted to prevail by their enchantments as far as the sign of frogs.
