Acts 2:2-6

And suddenly a noise like a violent rushing wind came from heaven, and it filled the whole house where they were sitting.

And tongues that looked like fire appeared to them, distributing themselves, and a tongue rested on each one of them.

And they were all filled with the Holy Spirit and began to speak with different tongues, as the Spirit was giving them the ability to speak out.

Now there were Jews residing in Jerusalem, devout men from every nation under heaven.

And when this sound occurred, the crowd came together and they were bewildered, because each one of them was hearing them speak in his own language.
