Understanding the history of Jerusalem is important for us today because we can liken it to our own circumstances. I highly recommend the DVD called Journey of Faith which talks about the scholarly view of the exodus made by Lehi and his family from Jerusalem.
Here is a great preview of the movie:
There is also a follow up DVD called Journey of Faith: The New World which is worth seeing too.
I think that the information contained in these DVD’s can help the viewer become familiar with the land area, customs, and traditions, and many other conditions that influenced the writers of the Book of Mormon, especially Lehi and Nephi.
