Acts 2:1-8

When the day of Pentecost had come, they were all together in one place, and suddenly a sound came from heaven like a rushing violent wind, and it filled the whole house where they were sitting. There appeared to them tongues resembling fire, which were being distributed [among them], and they rested on each one of them [as each person received the Holy Spirit]. And they were all filled [that is, diffused throughout their being] with the Holy Spirit and began to speak in other tongues (different languages), as the Spirit was giving them the ability to speak out [clearly and appropriately]. Now there were Jews living in Jerusalem, devout and God-fearing men from every nation under heaven. And when this sound was heard, a crowd gathered, and they were bewildered because each one was hearing those in the upper room speaking in his own language or dialect. They were completely astonished, saying, “Look! Are not all of these who are speaking Galileans? Then how is it that each of us hears in our own language or native dialect?
