2:4 All of them were filled with the Holy Spirit, and they began to speak in other languages as the Spirit enabled them.

2:5 Now there were devout Jews from every nation under heaven residing in Jerusalem. 2:6 When this sound occurred, a crowd gathered and was in confusion, because each one heard them speaking in his own language. 2:7 Completely baffled, they said, “Aren’t all these who are speaking Galileans? 2:8 And how is it that each one of us hears them in our own native language? 2:9 Parthians, Medes, Elamites, and residents of Mesopotamia, Judea and Cappadocia, Pontus and the province of Asia, 2:10 Phrygia and Pamphylia, Egypt and the parts of Libya near Cyrene, and visitors from Rome, 2:11 both Jews and proselytes, Cretans and Arabs – we hear them speaking in our own languages about the great deeds God has done!”
