And when the day of
Pentecost was fully come, they were
all with one accord in one place.
And suddenly there came a sound from
heaven as of a rushing mighty wind,
and it filled all the house where
they were sitting. And there
appeared unto them cloven tongues
like as of fire, and it sat upon
each of them. And they were all
filled with the Holy Ghost, and
began to speak with other tongues,
as the Spirit gave them utterance.
Acts 2:1-4 (NKJV)
