Numbers 35:6-8  New English Translation

⁶ Now from these towns that you will give to the Levites you must select six towns of refuge to which a person who has killed someone may flee.^[a] And you must give them forty-two other towns.

⁷ “So the total of the towns you will give the Levites is forty-eight. You must give these together with their grazing lands. ⁸ The towns you will give must be from the possession of the Israelites. From the larger tribes you must give more; and from the smaller tribes fewer. Each must contribute some of its own towns to the Levites in proportion to the inheritance allocated to each.
