The word "Ba'al" literally means "lord" or "ruler", which was probably the initial origin of this name. It's fitting then that Bael, most commonly known by the name Beelzebub, was considered the highest ranked figure of the 72 demons in the Lesser Key of Solomon, which made him presumably second in power only to Satan himself. The full name "Beelzebub" comes from the words "Ba'al" and "Zebub", which together mean "Lord of the Flies". Gods-and-Monsters.com
