Brief overview and citation of the event of Pentecost as described in Acts 2:1-4, including historical context and the significance of the day.

The event of Pentecost is described in Acts 2:1-4, where it is said that on the day of Pentecost, the disciples of Jesus were gathered together in one place when suddenly a sound like a rushing wind came from heaven and filled the whole house where they were sitting. Tongues of fire appeared and rested on each of them, and they were all filled with the Holy Spirit and began to speak in other languages.

Historically, Pentecost was a Jewish festival that took place 50 days after Passover, celebrating the giving of the Law to Moses on Mount Sinai. The significance of the day in the Christian context is that it marks the coming of the Holy Spirit upon the disciples, empowering them to spread the message of Jesus to people of all nations. This event is often seen as the birth of the Christian church and is celebrated as the feast of Pentecost in many Christian traditions.
