בעל זבוב

Etymology
From +, appearing in the Hebrew Scriptures as the purported name of a deity worshipped by the Philistines in Ekron. It's likely this was not the god's actual name and instead was a polemic against the deity, possibly by associating the figure with defecation (hence flies).

Proper noun

 * 1) Beelzebub, the lord of the flies, a Philistine god sometimes identified by Jews and Christians with Satan
