Numbers 35:4-6

Evangelical Heritage Version

⁴ The pasturelands of the cities, which you will give to the Levites, will extend out from the wall of the city 500 yards^[a] in all directions. ⁵ As the eastern boundary you will measure 1000 yards^[b] in addition to the size of the city, 1000 yards as the southern boundary, 1000 yards as the western boundary, and 1000 yards as the northern boundary. The city is in the middle. This area will serve as the pasturelands of their cities.

⁶ The cities which you will give to the Levites will include six cities of refuge, which you will provide so that a person who has killed someone may flee there. In addition to these six cities, you will give them forty-two other cities.
