Acts 2:1-7, 14-15, 41
When the day of Pentecost had come, they were all together in one place. And suddenly from heaven there came a sound like the rush of a violent wind, and it filled the entire house where they were sitting. Divided tongues, as of fire, appeared among them, and a tongue rested on each of them. All of them were filled with the Holy Spirit and began to speak in other languages, as the Spirit gave them ability.
Now there were devout Jews from every nation under heaven living in Jerusalem. And at this sound the crowd gathered and was bewildered, because each one heard them speaking in the native language of each. Amazed and astonished, they asked, “Are not all these who are speaking Galileans? And how is it that we hear, each of us, in our own native language?
All were amazed and perplexed, saying to one another, “What does this mean?” But others sneered and said, “They are filled with new wine.” But Peter, standing with the eleven, raised his voice and addressed them, “Men of Judea and all who live in Jerusalem, let this be known to you, and listen to what I say. Indeed, these are not drunk, as you suppose, for it is only nine o’clock in the morning….Peter went on and preached about many things that day. Those who welcomed his message were baptized, and that day about three thousand persons were added. They devoted themselves to the apostles’ teaching and fellowship, to the breaking of bread and the prayers.
