Cities of Refuge

"Six of the towns you give the Levites
will be cities of refuge,
to which a person who has killed someone may flee.
In addition, give them forty-two other towns.
In all you must give the Levites forty-eight towns,
together with their pasturelands.
The towns you give the Levites
from the land the Israelites possess
are to be given in proportion
to the inheritance of each tribe:
Take many towns from a tribe that has many,
but few from one that has few."

Then the Lord said to Moses:
"Speak to the Israelites and say to them:
'When you cross the Jordan into Canaan,
select some towns to be your cities of refuge,
to which a person
who has killed someone accidentally may flee.
They will be places of refuge from the avenger,
so that a person accused of murder
may not die before he stands trial before the assembly.
These six towns you give will be your cities of refuge.
Give three on this side of the Jordan
and three in Canaan as cities of refuge.
These six towns will be a place of refuge for Israelites,
aliens and any other people living among them,
so that anyone
who has killed another accidentally can flee there."

(Numbers 35:6-15)
