So it ought to be read in Matthew 12:24; Mark 3:22; Luke 11:15, etc. The Jews, in ridicule, changed Baalzebub, the Ekronite "god of flies", into Beelzebul, "god of dung" (which however is zebel, as they changed Beth-el ("house of God") into Beth-aven ("house of vanity"), when the golden calf was set up there. Zebul means "dwelling," lord of this lower world, "prince of the power of the air" (Ephesians 2:2), and taking up his "dwelling" in human bodies (Matthew 12:45).

Thus "master of the house" and "master of the dwelling" (Beelzebul) stand in happy contrast (Matthew 10:25). As the Ekronite god was applied to by Ahaziah to east, out his disease, so the Jews taunted Jesus as using the same idol power to east out demons. Idols and demons, moreover, had a close connection (1 Corinthians 10:20-21). Beelzebul was thought to be the foul prince of both.
