Acts 2:3-6

³and there appeared to them tongues as of fire, distributing themselves; and one sat upon each of them.

⁴And they were all filled with the Holy Spirit, and began to speak with other tongues, even as the Spirit gave them utterance.

⁵Now there were dwelling at Jerusalem Jews, devout men, from every nation under heaven.

⁶And when this sound took place, the multitude came together, and were confounded, because every one heard them speaking in his own language.
