Issi b. Yehudah says: It is written here "horse," unqualified (i.e., the punishments of the horse are not specified), and, elsewhere, "horse," qualified, viz. (Zechariah 12:4) "I will smite every horse with craze, and its rider with distraction. But I will open My eyes to the house of Yehudah, and every horse of the peoples I will smite with blindness," and (Ibid. 14:12) "And this will be the plague with which the L–rd will strike all the peoples who massed against Jerusalem, etc.", and (Ibid. 15) "And thus (i.e., as that of the men) will be the plague of the horse, the mule, the camel, and the ass, etc." Just as in the qualified, five smitings, so, in the unqualified, five smitings.
