Acts 2:1-4

1When Pentecost, the fiftieth day after Passover, came, all the believers were together in one place.

2Suddenly, a sound like a violently blowing wind came from the sky and filled the whole house where they were staying.

3Tongues that looked like fire appeared to them. The tongues arranged themselves so that one came to rest on each believer.

4All the believers were filled with the Holy Spirit and began to speak in other languages as the Spirit gave them the ability to speak.
