Numbers 35:2-5

CLV(i) 2 Instruct the sons of Israel so that they give to the Levites, from the allotment of their holding, cities to dwell in; and by the cities, common pasture land around them shall you give to the Levites. 3 The cities will be theirs to dwell in, and their common lands shall be for their domestic beasts, for their goods and for all their animals. 4 The common lands of the cities which you shall give to the Levites will extend from the sidewall of the city outward a thousand cubits round about. 5 You will measure off outside the city on the eastward edge two thousand cubits, on the southward edge two thousand cubits, on the western edge two thousand cubits and on the northern edge two thousand cubits with the city in the middle. This shall be their common lands for the cities.
