And there were dwelling at Jerusalem Jews, devout men, out of every nation under heaven.
Read Chapter 2
John Chrysostom
AD 407
The fact of their dwelling there was a sign of piety: that being of so many nations they should have left country, and home, and relations, and be abiding there. For, it says, There were dwelling at Jerusalem Jews, devout men, out of every nation under heaven. Now when this was noised abroad, the multitude came together, and were confounded.
