NOT UNUSUAL?!?!Good grief.
And they were all amazed and marvelled, saying one to another, Behold, are not all these which speak Galilaeans? And how hear we every man in our own tongue, wherein we were born? Parthians, and Medes, and Elamites, and the dwellers in Mesopotamia, and in Judaea, and Cappadocia, in Pontus, and Asia, Phrygia, and Pamphylia, in Egypt, and in the parts of Libya about Cyrene, and strangers of Rome, Jews and proselytes, Cretes and Arabians, we do hear them speak in our tongues the wonderful works of God.

Luke identifies sixteen different languages or distinct local dialects over which the Apostles gained Power that day, and that's just the listing which he cared to mention.
Rustic aramaic-speaking Galilean fishermen do not speak 16 different languages. It would not only be unusual, it would be unheard-of.
It would be a Miracle.
It would be the gift of Power over Foreign Tongues.
Why not "How do they speak all our languages?" Were the 120 speaking 16 different languages at the same time? Each a different one or all in unison? You mean they were amazed and marvelled because the 120 suddenly somehow learned some 16 languages? And some were so impressed with this accomplishment that they decided drunkeness can cause one to suddenly speak 16 different languages? Come on, If I told you I speak 16 different languages since I woke up this morning, would you drop to your knees and praise God? How about me and my whole family?Of course not.
That is why I have believed that it was a gift of being able to hear the gospel...so many languages...and yet each man heard it in his own language (and dialect??)awesome...
