Horse and Rider Rising to Heaven and Plunging to the Deep as One

Another interpretation: Is it only one horse and one rider? Has it not already been said, "He took six hundred chariots" (Exodus 14:7), "the chariots of Pharaoh and his army" (Exodus 15:4)? Rather, when Israel does the will of the Omnipresent, their enemies before them are no more than a single horse and its rider. Similarly you say, "When you go out to war against your enemy and see horse and chariot" (Deuteronomy 20:1). Is it only one horse and one chariot? Has it not already been said, "a people more numerous than you"? Rather, when Israel does the will of the Omnipresent, and so forth. "The horse and its rider": this tells that the horse was bound to the chariot and the chariot bound to the horse, and they would rise to the heights and descend to the depths, and they were not separated one from the other. A parable: a person throws two vessels into the air; in the end one of them is bound to part from its fellow. But here, "He cast and He shot" (cf. Exodus 15:4): "cast," for they were rising to the heights; "shot," for they were descending to the depths, and they were not separated one from the other. One verse says "cast" and another verse says "shot." How can these two verses be reconciled? "Cast," for they were rising upward; "shot," for they were going downward.
