Matthew 9:31

Then after their cure He commands them to tell no man; neither doth He merely command them, but with much strictness. "For Jesus," it is said, "straitly charged them, saying, See that no man know it. But they, when they were departed, spread abroad His fame in all that country." They however did not endure this, but became preachers, and evangelists; and when bidden to hide what had been done, they endured it not. And if in another place we find Him saying, "Go thy way, and declare the glory of God," that is not contrary to this, but even highly in agreement herewith. For He instructs us to say nothing ourselves, concerning ourselves, but even to forbid them that would eulogise us: but if the glory be referred to God, then not only not to forbid, but to command men to do this.

The Lord from humility shunning the fame of His glorious works, gave them this charge, and they from gratitude cannot be silent respecting so great benefit.

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.

(Mor. xix. 23.) We must enquire how this is that the Almighty, whose will and power are coextensive, should have here willed that His excellent works should be hid in silence, and is yet preached against His will, as it were, by these men who have received their sight. It is only that He herein has left an example to His servants who follow Him, that they should desire their own good deeds to be hid, and that notwithstanding they should be made known against their will, that others may profit by their example. They should then be hid by design, and published of compulsion; their concealment is by our own watchfulness, their betrayal is for others' profit.
