Deuteronomy is one of the more interesting books of the OT for demonstrating the attitude, beliefs and theology of the people at the time it was written. Throughout, it is very polytheistic, recognizing that there are multiple gods and the various gods are all powerful and can perform miracles, have valid and accurate prophets and in general, are equals. It shows the relationship between the Hebrews and the Hebrew GOD to be based on loyalty, not on the fact that the Hebrew GOD is somehow superior to the other gods.
