Acts 2:5

there were dwelling at Jerusalem, &c. Probably, in addition to the visitors, many religious Jews from foreign parts were permanent residents in Jerusalem, for it was to the Jew a thing much to be desired, that he might die and be buried near the Holy City. It is said (T. B. Kethuboth, III a), "Everyone that is buried in the land of Israel is in as good case as if he were buried under the altar," and there are many other like expressions in the immediate context of this quotation. That among the crowd were some residents seems the more likely, because when they recognized the new tongues, some asked as though they were acquainted with the speakers, "Are not these men Galilæans?"

devout men The adjective is used of the aged Simeon (Luke 2:25), and of the men who carried Stephen to his burial (Acts 8:2).

out of every nation under heaven Hyperbole, as we use from every part of the world. So (Josephus, B. Jud. ii. 16. 4) Herod Agrippa says, "There is not a nation in the world which does not contain some of us" (Jews). Cp. Acts 2:10, note on Libya.
