Of course, I hit submit, and I immediatly see one of the books that I couldn't find
Pre-exile, God was resposible for all, both good and evil. Satan refered to a different aspect of a singular being and was rarely mentioned. Post exile, God became the embodiment of Good, and Satan became the embodiment of Evil.
illustrating the change:
2 Sam 24:1 (10c-7c BCE)
Once again the Issraelites felt the
Lord's anger, when he incited David against them and gave him orders that Israel and Judah should be counted.
1 Chron 21:1 (4c BCE)
Now
Satan, setting himself against Israel, incited David to count the people.
I was mistaken about Lucifer, also. His only mention in the bible comes in Isaiah 14:12, and his very name is a mistranslation of "Day star, son of the Dawn" and was most likely a reference to a babylonian king. Lucifer the angel was integrated into the doctrine of the fall, and was thus immortalized.
Don't have any more info on Bealzubub, sadly.
There is also an interesting text outlining the doctrine of the fall, and the host of angels, although I can't recall the name or the author atm. If I think of it soon, I'll pm it to you or post here yet again. Hoped this helped some.
