The bottom line is that Deuteronomy is a late revision of ancient law. And what is so striking and so vital in all of this is that whoever was responsible for Deuteronomy apparently had no hesitation whatsoever in updating older laws for new situations and still calling it the words that God spoke back then to Moses on Mt. Sinai (or Horeb, as it is called in Deuteronomy), even though they don’t match what God said in Exodus.
