Acts 2:1–4 (CSB)

1 When the day of Pentecost had arrived, they were all together in one place. 2 Suddenly a sound like that of a violent rushing wind came from heaven, and it filled the whole house where they were staying. 3 They saw tongues like flames of fire that separated and rested on each one of them. 4 Then they were all filled with the Holy Spirit and began to speak in different tongues, as the Spirit enabled them.
