Beelzebub or Beel-Zebub (/biːˈɛlzᵻbʌb/ bee-el-zə-bub or /ˈbiːlzᵻbʌb/ beel-zə-bub; Hebrew: בַּעַל זְבוּב, Baʿal Zəvûv; Arabic: بعل الذباب, Ba‘al adh-dhabâb) is a contemporary name for the devil. Ba‘al Zəbûb is variously understood to mean "lord of the flies" or "lord of the (heavenly) dwelling". Originally the name of a Philistine god, Ba'al, meaning "Lord" in Ugaritic, was used in conjunction with a descriptive name of a specific god. The Septuagint renders the name as Baalzebub (βααλζεβούβ) and as Baal muian (βααλ μυιαν, "Baal of flies"), but Symmachus the Ebionite may have reflected a tradition of its offensive ancient name when he rendered it as Beelzeboul.
In Christian and Biblical sources, Beelzebub is another name for the devil. In Christian demonology, he is one of the seven princes of Hell according to Catholic views on Hell. The Dictionnaire Infernal describes Beelzebub as a demonic fly who is also known as the "Lord of the Flies". The god of the Philistine city of Ekron, a Canaanite god.
