Matthew 9:27

Wherefore can it be that He puts them off, and they crying out? Here again teaching us utterly to repel the glory that cometh from the multitude. For because the house was near, He leads them thither to heal them in private. And this is evident from the fact, that He charged them moreover to tell no man. But this is no light charge against the Jews; when these men, though their eyes were struck out, receive the faith by hearing alone, but they beholding the miracles, and having their sight to witness what was happening, do all just contrary. And see their earnestness also, both by their cry, and by their prayer itself. For they did not merely approach Him, but with loud cries, and alleging nought else but "mercy." And they called Him "Son of David," because the name was thought to be honorable. In many passages, for instance, did the prophets likewise so call the kings, whom they wished to honor, and to declare great.

The miracles that had gone before of the ruler's daughter, and the woman with the issue of blood, are now followed by that of two blind men, that what death and disease had there witnessed, that blindness might now witness. And as Jesus passed thence, that is, from the ruler's house, there followed him two blind men, crying, and saying, Have mercy on us, thou Son of David. Let Marcion and Manichæus, and the other heretics who mangle the Old Testament, hear this, and learn that the Saviour is called the Son of David; for if He was not born in the flesh, how is He the Son of David?

Allegorically; By these two blind men are denoted the two nations of Jews and Gentiles, or the two nations of the Jewish race; for in the time of Roboam his kingdom was Split into two parts. Out of both nations such as believed on Him Christ gave sight to in the house, by which is understood the Church; for without the unity of the Church no man can be saved. And they of the Jews who had believed the Lord's coming spread the knowledge thereof throughout the whole earth.

Rightly they call Him Son of David, because the Virgin Mary was of the line of David.

The house of the ruler is the Synagogue which was ruled by Moses; the house of Jesus is the heavenly Jerusalem. As the Lord passed through this world and was returning to His own house, two blind men followed Him; that is, when the Gospel was preached by the Apostles, many of the Jews and Gentiles began to follow Him. But when He ascended into Heaven, then He entered His house, that is, into the confession of one faith which is in the Catholic Church, and in that they were enlightened.
