Acts 13:40

40, 41. This passage in Paul's speech was most unwelcome to his Jewish hearers. It was an express disparagement of the law of Moses such as always fell harshly upon Jewish ears. We consequently see in the next and last paragraph of the speech an indication of a change in the aspect of the audience. It is only an audience in whom a most unfavorable change is discernible, that so watchful a speaker could address in these words: (40) "Beware, then, lest that which is said in the prophets come upon you; (41) Behold, ye despisers, and wonder and perish; for I do a work in your days, a work which you will not believe though one should fully declare it to you." No doubt some evidence of their incredulity was visible in their countenances, if it was not exhibited by audible murmurings. The force of the quotation was to show, that if they did reject the gospel, they would only be identifying themselves with a class of whom this conduct had been predicted.

The surprise expressed by the prophet, that they would not believe though one should declare it to them, does not assume that they should believe facts so astounding upon the mere assertion of an individual; but the object of surprise is, that they would not believe though one should declare it fully to them, that is, with all the incontestable evidences of its reality. Undoubtedly the work referred to by the apostle, in his application of the prophet's language, is the work of raising up a savior to Israel in the person of Jesus.
