Here you can find bible notes broken down by book and further by chapter. It is suggested to have a hard copy of KJV on hand to understand the references to the notes I'm making.
Book of Daniel
Chapter 2 continued
Apocrypha related to Book of Daniel:
Bel and the Dragon
Bel and the Dragon is a quick read, and a good story about idolatry. It is worth reading, in my opinion.
Note on apocrypha, I think it's fine to read it as an extra thing (using discernment, as always), but there's probably a reason it's not in the standard KJV we have today. In this instance, I think the story just doesn't really fit anywhere within the 12 chapters we have. To me, the book of Daniel already felt like a bunch of different sources being put together into one peice. So I think this was probably just something extra that didn't make the cut.
