New Defender's Study Bible Notes
2:5 dwelling at Jerusalem. The verb here does not convey the meaning of temporary lodging, as though these men had just come to Jerusalem for the feast days, but rather permanent dwellings. These were devout Jews, who had decided, for religious reasons, to move back to Jerusalem from the various foreign lands where they had been raised (Acts 2:8), their ancestors having been deported from Israel in earlier times. There may also have been temporary visitors from these other lands, lodging during the feast days with their Jerusalem friends and relatives.
