"When the day of Pentecost had come, they were all together in one place. ²And suddenly from heaven there came a sound like the rush of a violent wind, and it filled the entire house where they were sitting. ³Divided tongues, as of fire, appeared among them, and a tongue rested on each of them. ⁴All of them were filled with the Holy Spirit and began to speak in other languages, as the Spirit gave them ability.

5 Now there were devout Jews from every nation under heaven living in Jerusalem. ⁶And at this sound the crowd gathered and was bewildered, because each one heard them speaking in the native language of each. ⁷Amazed and astonished, they asked, ‘Are not all these who are speaking Galileans? ⁸And how is it that we hear, each of us, in our own native language? ⁹Parthians, Medes, Elamites, and residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, ¹⁰Phrygia and Pamphylia, Egypt and the parts of Libya belonging to Cyrene, and visitors from Rome, both Jews and proselytes, ¹¹Cretans and Arabs—in our own languages we hear them speaking about God’s deeds of power.’ ¹²All were amazed and perplexed, saying to one another, ‘What does this mean?’¹³But others sneered and said, ‘They are filled with new wine.’"
