6 When they heard this sound, a crowd came together in bewilderment, because each one heard their own language being spoken.
6 And at this sound the multitude came together, and they were bewildered, because each one was hearing them speak in his own language.
6 When they heard the sound, they came on the run. Then when they heard, one after another, their own mother tongues being spoken, they were thunderstruck.
6 And when this sound occurred, the multitude came together, and were confused, because everyone heard them speak in his own language.
6 When they heard the loud noise, everyone came running, and they were bewildered to hear their own languages being spoken by the believers.
Matthew Henry's Commentary on Acts 2:6
Commentary on Acts 2:5-13
(Read Acts 2:5-13)
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.
