Acts 2:1-4

When the day of Pentecost came, all the believers were gathered together in one place. Suddenly there was a noise from the sky which sounded like a strong wind blowing, and it filled the whole house where they were sitting. Then they saw what looked like tongues of fire which spread out and touched each person there. They were all filled with the Holy Spirit and began to talk in other languages, as the Spirit enabled them to speak.
