Beelzebub
Old English Belzebub, Philistine god worshipped at Ekron (2 Kings i:2), from Latin, used in Vulgate for New Testament Greek beelzeboub, from Hebrew ba'al-z'bub "lord of the flies," from ba'al "lord" + z'bhubh "fly." By later Christian writers often taken as another name for "Satan," though Milton made him one of the fallen angels.
