5 At that time there were devout Jews from every nation living in Jerusalem. 6 When they heard the loud noise, everyone came running, and they were bewildered to hear their own languages being spoken by the believers. 7 They were completely amazed. "How can this be?" they exclaimed. "These people are all from Galilee, 8 and yet we hear them speaking in our own native languages! 9 Here we are-Parthians, Medes, Elamites, people from Mesopotamia, Judea, Cappadocia, Pontus, the province of Asia, 10 Phrygia, Pamphylia, Egypt, and the areas of Libya around Cyrene, visitors from Rome 11 (both Jews and converts to Judaism), Cretans, and Arabs. And we all hear these people speaking in our own languages about the wonderful things God has done!" 12 They stood there amazed and perplexed. "What can this mean?" they asked each other. 13 But others in the crowd ridiculed them, saying, "They're just drunk, that's all!"

The difference in languages which arose at Babel, has much hindered the spread of knowledge and religion. The instruments whom the Lord first employed in spreading the Christian religion, could have made no progress without this gift, which proved that their authority was from God.
