Acts 2:1-4

When the day of Pentecost had arrived, they were all together in one place. Suddenly a sound like that of a violent rushing wind came from heaven, and it filled the whole house where they were staying. And tongues, like flames of fire that were divided, appeared to them and rested on each one of them. Then they were all filled with the Holy Spirit and began to speak in different languages, as the Spirit gave them ability for speech.
