Numbers 35:1-5

The LORD spoke to Moses in the plains of Moab by the Jordan at Jericho, saying, “Command the people of Israel to give to the Levites some of the inheritance of their possession as cities for them to dwell in. And you shall give to the Levites pasturelands around the cities. The cities shall be theirs to dwell in, and their pasturelands shall be for their cattle and for their livestock and for all their beasts. The pasturelands of the cities, which you shall give to the Levites, shall reach from the wall of the city outward a thousand cubits all around. And you shall measure, outside the city, on the east side two thousand cubits, and on the south side two thousand cubits, and on the west side two thousand cubits, and on the north side two thousand cubits, the city being in the middle. This shall belong to them as pastureland for their cities.
