When the day of Pentecost came, they were all together in one place. Suddenly a sound like the blowing of a violent wind came from heaven and filled the whole house where they were sitting. They saw what seemed to be tongues of fire that separated and came to rest on each of them. All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them.
Now there were staying in Jerusalem God-fearing Jews from every nation under heaven. When they heard this sound, a crowd came together in bewilderment, because each one heard their own language being spoken... Amazed and perplexed, they asked one another, “What does this mean?” Some, however, made fun of them and said, “They've had too much wine.”
Then Peter stood up, raised his voice, and addressed the crowd: “Fellow Jews and all of you who live in Jerusalem, let me explain this to you; listen carefully to what I say. These people aren't drunk... It’s only nine in the morning!
I guess Peter didn't know that it's always 5 o'clock somewhere.
