Acts 2: 2 - 4, 11
2 And suddenly a sound came from heaven like the rush of a mighty wind, and it filled all the house where they were sitting.
3 And there appeared to them tongues as of fire, distributed and resting on each one of them.
4 And they were all filled with the Holy Spirit and began to speak in other tongues, as the Spirit gave them utterance.
11 Cretans and Arabians, we hear them telling in our own tongues the mighty works of God."
