Acts 2:1-4 "And when the day of Pentecost was fully come,
they were all with one accord in one place. And suddenly there
came a sound from heaven as of a rushing mighty wind, and it
filled all the house where they were sitting. And there
appeared unto them cloven tongues like as of fire, and it sat
upon each of them. And they were all filled with the Holy
Ghost, and began to speak with other tongues, as the Spirit
gave them utterance."

Acts 2:6-11 "Now when this wqas noised abroad, the
multitude came together, and were confounded, because that
every man heard them speak in his own language. And they
were all amazed and marveled, saying one to another,
Behold, are not all these which speak Galileans? And how
hear we every man in our own tongue, wherein we were born?
Par'thi-ans, and Medes, and E'lamites, and the dwelllers in
Mesopota'mi-a, and in Judea, and Cappado'cia, in Ontus, and
Asis, Phyrig'i-a, and Pamphyl'i-a, in Egypt, and in the parts of
Libya about Cyre'ne, and strangers of Rome, Jews and
proselytes, Cretes and arabians, we do hear them speak in
our tongues the wonderful workd of God."
(Are "tongue" languages of gibberish?)
