Deuteronomy 1:2 - Matthew Poole's English Annotations on the Holy Bible

This is added to show that the reason why the Israelites in so many years were advanced no further from Horeb than to these plains, was not the great distance of the places or length of the way, which was but a journey of eleven days at most, but because of their rebellions, as is mentioned before and repeated in this book. Horeb, or Sinai, the place where the law was given, which is promiscuously called by both those names. Mount Seir, or Mount Edom, i.e. the mountainous country of Seir, which was first possessed by the Horims, and afterwards by the Edomites, Deuteronomy 2:12. Kadesh-barnea was not far from the borders of Canaan. See Genesis 16:14 Numbers 13:26.
