10 Phrygia and Pamphylia, Egypt and the parts of Libya belonging to Cyrene, and visitors from Rome, both Jews and proselytes, 11 Cretans and Arabs-in our own languages we hear them speaking about God's deeds of power." 12 All were amazed and perplexed, saying to one another, "What does this mean?"
Matthew Henry's Commentary on Acts 2:10-12
Commentary on Acts 2:5-13
(Read Acts 2:5-13)
