Who is Beelzebub?
The name properly should be Beelzebul in all the N. T. passages. Matt 10:25; Matt 12:24, Matt 12:27; Mark 3:22; Luke 11:15, 1 Sam 30:18, Acts 1:19. But this is, some say, merely because to the Greek tongue the latter form was easier. This name was in common use among the Jews in Christ's day as a title of Satan as the "prince of the demons." It means "lord of the house." Those who regard Beelzebul as a corruption of Baalzebub (lord of flies), the god of the Ekronites, 2 Kgs 1:3, worshipped as the patron deity of medicine, interpret it "lord of dung" or "filth," and explain the change in the name by the contempt of the Jews.
