John Chrysostom

And besides, the sequel is enough to bear him out on this point: so now the discourse is for all in common. "But this is that which was spoken by the prophet Joel, And it shall come to pass in the last days, saith the Lord God." Nowhere as yet the name of Christ, nor His promises but the promise is that of the Father. Observe the wisdom: observe the considerate forbearance. He did not pass on to speak at once of the things relating to Christ; that He had promised this after His Crucifixion; truly that would have been to upset all. And yet, you will say, here was sufficient to prove His divinity. True, it was, if believed (and the very point was that it should be believed); but if not believed, it would have caused them to be stoned.

And he added nothing, but, "This," says he, "is that which was spoken by the prophet Joel; And it shall come to pass in the last days." He shows, in fact, that the consummation is nigh at hand, and the words, "In the last days," have a kind of emphasis.
