Acts 2:7

Since the event had taken place in a house, of course they came together from without. The multitude was confounded: was all in commotion. They marvelled; "Because that every man heard them speak in his own language. And they were amazed," it says, "and marvelled, saying one to another, Behold, are not all these which speak Galileans?" They immediately turned their eyes towards the Apostles.

"Behold, are not all these which speak Galileans?" For indeed this was confessed. "And how hear we" so much did the sound alarm them. "Every man in our own tongue," etc. for it found the greater part of the world assembled there.

The multitude was perplexed or disturbed, for reasonably they supposed that wondrous things were being shown to them, on account of the bold deeds done concerning Christ, and conscience troubled their souls. And some were murderous in this way; but the devout ones were amazed, recognizing them as Galileans yet hearing them speak in their native tongues.

But the apostles knew what they were saying, namely the mighty works of God; as for the languages, they did not know them, except that the men who heard were devout, for example some Scythian by chance, or an Indian who understood the Scythian, or that the apostles spoke in the dialect of the Indians.

Everywhere alongside virtue there is vice. Some marveled, others reviled. The former were truly devout; they lived in Jerusalem precisely because the law permitted them to appear three times a year at the temple in Jerusalem.
