10 In Phrygia and Pamphylia, in Egypt and the parts of Libya about Cyrene, and those who have come from Rome, Jews by birth and others who have become Jews, 11 Men of Crete and Arabia, to all of us they are talking in our different languages, of the great works of God.
Matthew Henry's Commentary on Acts 2:10-11
Commentary on Acts 2:5-13
