Were dwelling (ēsan katoikountes). Periphrastic imperfect active indicative. Usually katoikeō means residence in a place (Act 4:16; Act 7:24; Act 9:22, Act 9:32) as in Act 2:14 (Luk 13:4). Perhaps some had come to Jerusalem to live while others were here only temporarily, for the same word occurs in Act 2:9 of those who dwell in Mesopotamia, etc.
Devout (eulabeis). Reverent (eu, well, lambanō, to take). See note on Luk 2:25 like Simeon waiting for the consolation of Israel or hoping to die and be buried in the Holy City and also Act 8:2.
