Acts 2:1-6 Describes the *event* so ... Could you please then interrupt Acts 2:6 Now when this was *noised abroad* (literally = this voice having come) the multitude came together, and were *CONFOUNDED*, because that every man heard them speak in his own language. ?????? Verse 9 describes the languages that were present that understood one voice in their own language. This does not speak about an unknown gibberish tongue rather one that everyone understood in their own language out of one mouth.
Which is precisely what the members of my Bible study class say happened to them.
But your INTERPRETATION (note, not "interrupt") is nuts. The ones who were "speaking in tongues" were the Apostles, not the Holy Spirit. And "noised abroad" usually means, "once word had spread"...
