Introduction to Exodus - Escape from slavery!

Paul and Laurence pick up from where the previous episode left off with a look at the book of Exodus. They find it's a book that starts with a great story about how the Israelites escaped from Egypt. There's high action, drama, goodies and baddies... and then intricate detail about how to construct a large tent. Why is that included?  How does that fit into the overall narrative?  Listen in to hear Paul and Laurence's ideas on that!
