Numbers 34 - 36
The Lord defines the boundaries of the land that Israel will inherit, and names the leaders of the tribes.
Forty eight cities are to be given to the Levites throughout the territory of Israel, with six of those cities designated as Cities of Refuge. Anyone who kills another inadvertently, or by accident can flee to the nearest city of refuge, and if he is judged innocent of murder, then he can live in that city and be protected from the avenger of blood (the nearest relative of the one who was killed).
However, when the High Priest dies, then all such refugees are free to go home, and the avenger of blood is no longer allowed to exact revenge. Each of us have been declared not-guilty as a consequence of our High Priest having died, and we were set free.
This book ends with a clarification of the laws of inheritance.
