Wrong
they spoke in tongues - 120 people all at the same time
Now when this was noised abroad, the multitude came together, and were confounded, because that every man heard them
speak in his own language. Acts 2:6
This is the miraculous gift of interpretation and again right from the beginning a sign of what was to come -
diversities of tongues, interpretations, prophecies.
God with mocking lips mocking the un regenerated Jews spoke in other nations languages other than Hebrew alone . The sign was against the Jew who refused to hear prophecy confirming their unbelief (no faith) even in the Hebrew their own language, they would stop up the ears like a deaf Adler and refuse to beleive God .
