Acts 2

1And when the day of Pentecost was fully come, they were all with one accord in one place.

2And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting.

3And there appeared unto them cloven tongues like as of fire, and it sat upon each of them.

4And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance.
