Beelzebub

Jews of New Testament times used “Beelzebub” as a name for Satan, the prince of demons (Matt 10:25; 12:24-27). It was a variation of the name Baal-zebub, a Baal god whose home (according to an ancient Canaanite belief) was in the Philistine town of Ekron (2 Kings 1:2). The name meant ‘lord of flies’, probably because the local people believed this god gave the citizens of Ekron protection against disease-carrying flies that plagues the area.

By contrast, other people interpreted the name in a bad sense - lord of flies, and therefore lord of filth. This was the meaning the Jews had in mind when they used the name as a title for Satan. Satan was Beelzebub, for he was lord of all things unclean, in particular unclean spirits, or demons (Mark 3:21-22; Luke 11:14-15).
