And their eyes were opened - Immediately. That is, their sight was restored: "And Jesus straitly charged them." He enjoined it on them in the most earnest and solemn manner.

See that no man know it - That is, do not make proclamation of this; do not make it your business to tell every man of it; do not go forth as if I wished that you should proclaim this abroad. The injunction could not mean that they should screen the fact that no one "should" know it, for there were witnesses of it, and it would be made known; but they were not to make it a point to proclaim to the world what was done to them. This was in accordance with the usual habit of the Saviour Matthew 8:4; Matthew 12:16, and also with his own precepts to others Matthew 6:1-4.

Straitly charged them - He charged them severely, from ενεβριμησατο, from εν, and βριμαομαι, to roar or storm with anger; he charged them, on pain of his displeasure, not to make it as yet public. See the reasons, Matthew 8:4.

And their eyes were opened,.... Some copies read, "immediately"; and so do the Syriac, Persic, and Ethiopic versions: and this was certainly the true and real matter of fact, that as soon as Christ had touched their eyes, and said the above words, their sight was perfectly restored to them; and they had a clear, full, and true sight of objects, as men have, whose vision faculty is in its full strength and rigour, and their eyes open:

and Jesus straitly charged them, saying, see that no man know it. This was a very strict charge, and according to the signification of the word here used, it was given with great austerity of countenance, and severity of expression, in a very rough and threatening manner; which Christ might be the rather induced to, because he had given such like orders already, and they had not been observed: the reasons for concealing the miracle are not very obvious; it seems likely, that with the same view he took no notice of these blind men in the street, but went into an house, and cured them; which seems to be, to shun all appearance of vain glory, or seeking popular applause, that he gave these orders; or it may be, he did not choose to be made more known by this miracle, or at this time, or by these men; he might foresee that it would be attended with ill consequences; either the more to irritate the resentments of some persons against him; or to put others on doing things which were disagreeable to him; as setting him up for a temporal prince among them, being David's son.

And their eyes were opened; and Jesus straitly charged them, saying, See that no man know it.

9:30,31 Jesus straitly charged them, etc. Their changed condition would sufficiently tell the story without their indiscreet babbling. They failed to obey, which they should have done, whether they understood the reason of the command or not. Note the three great lessons about our Lord: (1) He is the Life (Joh 11:25 14:6). He not only breaks the bonds of mortal death, but endows the soul with spiritual life. (2) He is the infallible Physician (Mr 2:17 Lu 5:31,32). Diseases of the body, sorrows of the heart, and sins of the soul that no man can heal, disappear at his touch. (3) He is the Light of the world (Joh 8:12). At his word sightless eyes see. At his word darkened souls are flooded with light.

30. And their eyes were opened: and Jesus straitly charged them-The expression is very strong, denoting great earnestness.

9:27-31 At this time the Jews expected Messiah would appear; these blind men knew and proclaimed in the streets of Capernaum that he was come, and that Jesus was he. Those who, by the providence of God, have lost their bodily sight, may, by the grace of God, have the eyes of their understanding fully enlightened. And whatever our wants and burdens are, we need no more for supply and support, than to share in the mercy of our Lord Jesus. In Christ is enough for all. They followed him crying aloud. He would try their faith, and would teach us always to pray, and not to faint, though the answer does not come at once. They followed Christ, and followed him crying; but the great question is, Do ye believe? Nature may make us earnest, but it is only grace that can work faith. Christ touched their eyes. He gives sight to blind souls by the power of his grace going with his word, and he puts the cure upon their faith. Those who apply to Jesus Christ, shall be dealt with, not according to their fancies, nor according to their profession, but according to their faith. Christ sometimes concealed his miracles, because he would not indulge the conceit which prevailed among the Jews, that their Messiah should be a temporal prince, and so give occasion to the people to attempt tumults and seditions.
