On the day of Pentecost, the apostles were filled with the Holy Spirit, and they spoke in tongues. This means that they were able to speak in languages they did not previously know, and the people from different regions who had gathered in Jerusalem for the feast of Pentecost were able to hear the message of the gospel in their own languages. This event was significant because it marked the beginning of the spread of Christianity to different parts of the world, and it fulfilled the prophecy of Joel that God would pour out his Spirit on all people.
