On the day of Pentecost, seven weeks after Jesus' resurrection, the believers were meeting together in one place.
Suddenly, there was a sound from heaven like the roaring of a mighty windstorm in the skies above them, and it filled the house where they were meeting.
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.
Godly Jews from many nations were living in Jerusalem at that time.
When they heard this sound, they came running to see what it was all about, and they were bewildered to hear their own languages being spoken by the believers.
