One of the podcasts I enjoy is The Naked Bible Podcast

Right now I am going through his series on the Book of Revelations covering all the references to the Old Testament.

You just have to suffer through the first 5 minutes of each podcast as they talk about the NFL, Packers, and Fantasy Football ... then a lecture style talk happens. :)

My favorite one this year has been his interview on the subject of Messiah Son of Joseph. I have just heard about this concept in the last 2 or 3 years. I guess the Rabbis don't talk about it openly since about 100AD.

The book is by David C. Mitchell, whom he interviews.
