#What did Yahweh command each one of the tribes of Israel to do for the Levites?

He commanded them to give to the Levites some of their own shares of land, cities to live in, and pastureland surrounding the cities. [35:1-2]

How would the cities of refuge protect an accused man from his avenger?

Anyone who killed someone unintentionally could flee to them and know they would not be killed without standing on trial before the community. [35:9-12}
