Numbers 35:4-6

Lexham English Bible

⁴ “The pasturelands of the cities that you will give to the Levites will extend from the wall of the city to a distance of a thousand cubits all around. ⁵ You will measure outside the city the eastern edge two thousand cubits, for the southern edge two thousand cubits, for the western edge two thousand cubits, and for the northern edge two thousand cubits, with the city in the middle; this will be for them the pasturelands of the cities.

⁶ “All the cities that you will give the Levites will be six cities of refuge, to which the killer can flee; in addition to them you will give forty-two cities.
