Numbers 35:1-5

While Israel was camped beside the Jordan on the plains of Moab across from Jericho, the LORD said to Moses, “Command the people of Israel to give to the Levites from their property certain towns to live in, along with the surrounding pasturelands. These towns will be for the Levites to live in, and the surrounding lands will provide pasture for their cattle, flocks, and other livestock. The pastureland assigned to the Levites around these towns will extend 1,500 feet from the town walls in every direction. Measure off 3,000 feet outside the town walls in every direction—east, south, west, north—with the town at the center. This area will serve as the larger pastureland for the towns.
