Numbers 34, 35, & 36

How does Numbers end? How is Canaan Israel's inheritance? How did the Canaanites lose their inheritance? How big was the Promised Land supposed to be? Why did God have Moses use Joshua and Eleazar to establish the boundaries for the tribes? Where were the Levites to live? How are the cities of refuge meant to stop violence? Do laws like these matter if they were never followed up on in scripture? What does it mean when a solution to a problem causes another problem?
