Numbers 35:5-7

Amplified Bible, Classic Edition

⁵ You shall measure from the wall of the city outward on the east, south, west, and north sides 2,000 cubits, the city being in the center. This shall belong to [the Levites] as [suburb] pasturelands for their cities.

⁶ Of the cities which you shall give to the Levites there shall be the six cities of refuge, which you shall give for the manslayer to flee into; and in addition to them you shall give forty-two cities.

⁷ So all the cities which you shall give to the Levites shall be forty-eight; you shall give them with their adjacent [suburb] pasturelands.
