When the day of Pentecost had come, they were all together in one place.
And suddenly from heaven there came a sound like the rush of a violent
wind, and it filled the entire house where they were sitting.
Divided tongues, as of fire, appeared among them, and a tongue rested on each of them.
All of them were filled with the Holy Spirit and began to speak in other languages, as the Spirit gave them ability. (Acts 2:1-4)
Violent wind, divided tongues as of fire, spontaneous language, amazement and questions, joy, concern, amazement, surprise, fear, awe, confusion, curiosity, glee, and even indifference.
