Acts 2:3

Now when the day of Pentecost had come, they were all with one accord in one place.

Suddenly there came from the sky a sound like the rushing of a mighty wind, and it filled all the house where they were sitting.

They were all filled with the Holy Spirit and began to speak with other languages, as the Spirit gave them the ability to speak.

Now there were dwelling in Jerusalem Jews, devout men, from every nation under the sky.

When this sound was heard, the multitude came together and were bewildered, because everyone heard them speaking in his own language.
