Dr Carly Crouch introduces the key themes is the Book of Deuteronomy. While we think of it a mainly a collection of laws and legal material, we should not lose sight of its two great themes. First, that Israel should only worship one God, Yahweh, and there must be no compromise allowing the worship of many gods. Second, that there is only one true cult site – although its location is not named in the book – and so there Israel is to reject local shrines and altars. The book can indeed be seen as setting out a vision of Israelite identity.
