A.T. Robertson Commentary Luke 4:44

"And he was preaching in the synagogues of Galilee." — Luke 4:44 (ASV)

Was preaching (ην κηρυσσων). Periphrastic imperfect active, describing his first tour of Galilee in accord with the purpose just stated. One must fill in details, though Mr 1:39 and Mt 8:23-25 tell of the mass of work done on this campaign.
