On the day of Pentecost all the believers were meeting together in one place. Suddenly, there was a sound from heaven like the roaring of a mighty windstorm, and it filled the house where they were sitting. Then, what looked like flames or tongues of fire appeared and settled on each of them. And everyone present was filled with the Holy Spirit and began speaking in other languages, as the Holy Spirit gave them this ability.
At that time there were devout Jews from every nation living in Jerusalem. When they heard the loud noise, everyone came running, and they were bewildered to hear their own languages being spoken by the believers.
