Acts 2:10

"Parthians, and Medes, and Elamites, and the dwellers in Mesopotamia, and in Judea, and Cappadocia, in Pontus, and Asia, Phrygia, and Pamphylia, in Egypt, and in the parts of Libya about Cyrene:" mark how they run from east to west: "and strangers of Rome, Jews and proselytes, Cretes and Arabians, we do hear them speak in our tongues the wonderful works of God."

This nerved the Apostles: for, what it was to speak in the Parthian tongue, they knew not but now learnt from what those said. Here is mention made of nations that were hostile to them, Cretans, Arabians, Egyptians, Persians: and that they would conquer them all was here made manifest. But as to their being in those countries, they were there in captivity, many of them: or else, the doctrines of the Law had become disseminated among the Gentiles in those countries. So then the testimony comes from all quarters: from citizens, from foreigners, from proselytes. "We do hear them speak in our tongues the wonderful works of God." For it was not only that they spoke in their tongues, but the things they spoke were wonderful.

Long after the old ark had overcome the waters of the sea, malicious people wished to extend their tower [of Babel] into heaven. In them, irreligious hearts divided the forms of their speech, and the good will in these arrogant confederates perished with their voice. At that time there was a confusion of language for a homogenous race; now there is one [language] for many since [that language] rejoices at the appearance of the coming church, [a language that] will have harmonious sounds; and [the church] brings about a return of eloquence in peace for the obedient [apostles], and the humble order gathers again what arrogant people scattered.

The Jews also and proselytes. Proselytes, that is, they called the newcomers those who, originating from the Gentiles, preferred to choose circumcision and Judaism, as is narrated that Achior did in the book of Judith. Therefore, they say, not only those who were Jews by nature had gathered from different parts of the world, but also those who, born from the foreskin, had embraced their rite.

And Roman sojourners. It would be more correctly rendered in Greek as And Roman wanderers, that is, Jews who were living in Rome as foreigners, just as others elsewhere, as mentioned above. For it is shown in the following verse that among those present were foreigners who are called proselytes in Greek, that is, those who from the nations had converted to Judaism, abandoning the rites of their own cultures, as it is said: Jews and proselytes as well.
