Acts 2:1-6 New Revised Standard Version (NRSV)
The Coming of the Holy Spirit
2 When the day of Pentecost had come, they were all together in one place. 2 And suddenly from heaven there came a sound like the rush of a violent wind, and it filled the entire house where they were sitting. 3 Divided tongues, as of fire, appeared among them, and a tongue rested on each of them. 4 All of them were filled with the Holy Spirit and began to speak in other languages, as the Spirit gave them ability.
5 Now there were devout Jews from every nation under heaven living in Jerusalem. 6 And at this sound the crowd gathered and was bewildered, because each one heard them speaking in the native language of each.
