Gill's Exposition of the Entire Bible:
And he said unto them, ye will surely say unto me this proverb,.... Or "parable"; for any pithy sentence, or proverbial expression, was, by the Jews, called a parable: physician heal thyself; and which was a proverb in use with the Jews; and which is sometimes expressed thus, , "go heal thyself" (m); and sometimes in this form, , "physician, heal thy lameness" (n): the meaning of which is, that a man ought to look at home, and take care of himself, and of those that belonged to him; and Christ was aware that his townsmen would object this to him, that if he was the person he was said to be, and could do the miracles and cures which were ascribed to him, he ought to do something of this kind at home, among them, who were his townsmen, neighbours, relations, and acquaintance; that is, heal their sick, lame, blind, leprous, deaf, and dumb: and that this is the sense of it, is manifest from what follows....
Jamieson-Fausset-Brown Bible Commentary:
23. this proverb—like our "Charity begins at home."
whatsoever, &c.—"Strange rumors have reached our ears of Thy doings at Capernaum; but if such power resides in Thee to cure the ills of humanity, why has none of it yet come nearer home, and why is all this alleged power reserved for strangers?"
Benson Commentary:
Luke 4:23-24. And he said, Ye will surely say — That is, your approbation now outweighs your prejudices. But it will not be so long. You will soon ask, why my love does not begin at home? why I do not work miracles here, rather than at Capernaum?
Expositor's Greek Testament:
Luke 4:23. πάντως, doubtless, of course—παραβολὴν = Hebrew mashal, including proverbs as well as what we call “parables”. A proverb in this case.—Ἰατρέ, etc.: the verbal meaning is plain, the point of the parable not so plain, though what follows seems to indicate it distinctly enough = do here, among us, what you have, as we hear, done in Capernaum. This would not exactly amount to a physician healing himself. We must be content with the general idea: every sensible benefactor begins in his immediate surroundings.
Cambridge Bible for Schools and Colleges:
Physician, heal thyself] The same taunt was addressed to our Lord on the Cross. Here it seems to have more than one application,—meaning, ‘If you are the Messiah why are you so poor and humble?’ or, ‘Why do you not do something for us, here in your own home?’ (So Theophylact, Euthymius, &c.)
Bengel's Gnomen:
Luke 4:23. Πάντως, by all means) Jesus is not caught or attracted by every kind of assent to His word: but presently subjoins remarks of such a kind, as that the hearers may be tested and proved by them. So John 8:32, where see the note.—ἐρεῖτε, ye will say) that is to say, this feeling, whereby ye say, Is not this Joseph’s son? will wax strong with you, when ye shall hear concerning my miracles. Comp. Matthew 13:54-55.[52] This is a metonymy of the consequent [for the antecedent], i.e. your unbelief [the antecedent] which ye now betray will prevent me, so that I shall not exhibit many miracles among you, as among others: then it shall be that you will be able to say [the consequent], Physician, heal thyself.—παραβολὴν) משל, a proverb.—σεαυτὸν, thyself) that is to say, what you have made good (performed) abroad, make good (perform) also at home, and in your own country.
