Acts 2:1-4 Amplified Bible, Classic Edition (AMPC)
2 And when the day of Pentecost had fully come, they were all assembled together in one place,
2 When suddenly there came a sound from heaven like the rushing of a violent tempest blast, and it filled the whole house in which they were sitting.
3 And there appeared to them tongues resembling fire, which were separated and distributed and which settled on each one of them.
4 And they were all filled (diffused throughout their souls) with the Holy Spirit and began to speak in other (different, foreign) languages (tongues), as the Spirit [a]kept giving them clear and loud expression [in each tongue in appropriate words].
Acts 2:1-4 New International Version (NIV)
The Holy Spirit Comes at Pentecost
2 When the day of Pentecost came, they were all together in one place. 2 Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting. 3 They saw what seemed to be tongues of fire that separated and came to rest on each of them. 4 All of them were filled with the Holy Spirit and began to speak in other tongues[a] as the Spirit enabled them.
