Explanation of the event as described in Acts 2:1-4:

In Acts 2:1-4, the event described is known as Pentecost. It takes place fifty days after Easter, when the disciples of Jesus were gathered together in one place. Suddenly, a sound like a rushing wind filled the room and tongues of fire appeared and rested on each of them. They were filled with the Holy Spirit and began to speak in different languages, as the Spirit enabled them. This event marked the beginning of the Christian church and empowered the disciples to spread the message of Jesus to people of all nations.
