When she lifts up herself high, she scorns the horse and his rider.

42. The ostrich raiseth her wings on high, when the synagogue opposes its Creator, not as before by dreading, but by now openly withstanding, Him. For being changed into the limbs of the devil, and believing the man of lies to be God, it exalts itself the higher against the faithful, the more it boasts also, that it is itself the body of God. And because it despises, not only the Manhood of the Lord, but also His very Godhead, it scorns, not merely the horseman, but the rider of the horseman also. For, without violating the unity of the Person, it can be understood that the Word of God then mounted the rider, when he created for Himself a living Body within the womb of the Virgin. He then mounted the horseman, when, by creating Himself, He brought under the yoke of Divine worship a human soul, possessing power over its own flesh. For the Godhead assumed the flesh, by the intervention of the soul, and by this means He held together the whole horseman; [S. Aug. de Fid. et Symb. §. 10.] because He joined together in Himself, not that only which was ruled, but that also which ruled. Judaea therefore, because, having been caught in the snare of seduction, by the coming of haughty Antichrist, it scoffs at our Redeemer, for having been lowly among men, scorns the horseman. But because it, in every thing, denies His Godhead, it scorns equally his rider also. But our Redeemer is, in one and the same person, both the horseman and the rider of the horseman; and, when He came into the world, He set forth mighty preachers against the world; and when, in the end of the world, He endures the craft of Antichrist, He supplies strength to those, who contend in His behalf: that so, when our ancient enemy is set free in that liberty of his which is speedily to be terminated, our faithful ones may receive so much greater strength, the more they have to fight against an adversary who has been let loose. Whence in this place, when the ostrich is described as raising her wings, and scorning the horseman and his rider, the mention of mighty preachers is immediately subjoined.
