Apostles describes how the Apostles were gathered together in a house.
Suddenly, a sound came from heaven like a rushing wind, filling the entire house, and tongues of fire appeared. Each tongue of fire sat upon an Apostle. The apostled were all filled with the Holy Spirit and began to speak in other languages.
During the Jewish Feast of Pentecost many people from throughout the Roman Empire were gathered in Jerusalem. On that day people heard their own languages being spoken by the Apostles. They were astonished, because some of these visitors spoke languages that were not widely spoken. Some people even thought that the Apostles were drunk.
The apostle Peter addressed the crowd. He explained how the Old Testament prophecies told about the coming of the Holy Spirit. He told people about Jesus Christ and His death and resurrection. On that day about three thousand people were baptized.
