5 Now there were dwelling at Jerusalem Jews, devout men, from every nation under heaven. 6 And when this sound was heard, the multitude came together, and were confounded, because that every man heard them speaking in his own language. 7 And they were all amazed and marvelled, saying, Behold, are not all these that speak Galilaeans? 8 And how hear we, every man in our own language wherein we were born? 9 Parthians and Medes and Elamites, and the dwellers in Mesopotamia, in Judaea and Cappadocia, in Pontus and Asia, 10 in Phrygia and Pamphylia, in Egypt and the parts of Libya about Cyrene, and sojourners from Rome, both Jews and proselytes, 11 Cretans and Arabians, we hear them speaking in our tongues the mighty works of God. 12 And they were all amazed, and were perplexed, saying one to another, What meaneth this?
