Acts 2:3-8

And there appeared unto them tongues parting asunder, like as of fire; and it sat upon each one of them. And they were all filled with the Holy Spirit, and began to speak with other tongues, as the Spirit gave them utterance. Now there were dwelling at Jerusalem Jews, devout men, from every nation under heaven. And when this sound was heard, the multitude came together, and were confounded, because that every man heard them speaking in his own language. And they were all amazed and marvelled, saying, Behold, are not all these that speak Galilæans? And how hear we, every man in our own language wherein we were born?
