The name Baal Zebub in the Bible
Etymology of the name Baal Zebub
The second part of the name Baal Zebub is the word זבוב (zebub), meaning fly:
Baal Zebub meaning
Baal Zebub literally means Lord Of The Fly (although Hebrew uses a singular form where in English a plural would be proper: Lord Of The Flies) but in effect it means Chaos Maker.
Since flies do not acknowledge authority this name is an empty title, and a good look at the behavior of flies may yield some insights in the workings of evil:
God's empire is like that of bees (the Hebrew word for bee, deborah is the feminine version of the masculine dabar, 'Word', Logos in Greek); bees have a house, are organized around centralized government, like flowers, make honey, speak a language, care for offspring, and are armed. Satan's 'empire' is like flies; flies are homeless, have no government, like dung and decaying flesh, make nothing, speak no language, don't care for their offspring, are not armed.
This name is a beautiful illustration of the core difference between God and satan, between the saved and the lost. The people that are saved, in the Biblical sense of the word, are part of an intertwined collection of souls called the Body of Christ. This Body is again a life form but of a higher plain; it's a singular entity with its own personality and spirit, and this mystery may perhaps be understood when we realize that every human being is in fact a huge colony of billions of single-cellular creatures. All these cells have at their core the same genetic blueprint, just like all members of the Body of Christ have the Word as their core. And just like these colonies that we are, have the single personality and single soul we identify ourselves with, so does the Bride of Christ.
The lost, however, are not connected, although they may readily huddle up and imagine they are united. The lost care only about themselves, like flies that scurry around on a carcass, and engage in business and science and the pursuit of happiness just like the saved. But the lost do not form an amalgamation with a single soul. Satan is called the ruler of this latter group, but since the group does not subject to a central rule, he can only cause greater chaos.
