Acts 2:4-8

4And 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].

5Now there were Jews living in Jerusalem, devout and God-fearing men from every nation under heaven.

6And 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.

7They were completely astonished, saying, “Look! Are not all of these who are speaking Galileans?

8Then how is it that each of us hears in our own language or native dialect?
