Numbers 35:12, 24, 25
You are to have these cities as a refuge from the avenger, so that the manslayer will not die until he stands trial before the assembly. / then the congregation must judge between the slayer and the avenger of blood according to these ordinances. / The assembly is to protect the manslayer from the hand of the avenger of blood. Then the assembly will return him to the city of refuge to which he fled, and he must live there until the death of the high priest, who was anointed with the holy oil.
