Luke
Acts 2:10ASV·traditional attribution

in Phrygia and Pamphylia, in Egypt and the parts of Libya about Cyrene, and sojourners from Rome, both Jews and proselytes,

John Gill Reformed Baptist

Phrygia and Pamphylia were countries in Asia, each with known borders and chief cities where Paul himself later travelled. Egypt is that great African land, and from Libya near Cyrene many Jews had come, though some dispute whether they spoke Egyptian or other tongues. Rome sent Jews and proselytes too, natives of that city, now at Jerusalem for the feast.

AI summary

Matthew Henry Presbyterian

Jerusalem was crowded with devout Jews and proselytes from every corner of the known world, some from eastern nations like Parthia and Mesopotamia, others from Cappadocia and beyond. God had made the city a rendezvous of religious people, just as other cities drew traders, so that witnesses to this miracle would carry word to all nations.

Geneva Bible Notes Reformed

By Jews, Luke means those born Jewish and professing the faith, though scattered abroad. The proselytes were Gentiles who had embraced the Jewish religion, two kinds of worshippers, one by birth, one by conversion.
