Num 35:1-8 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. “The cities that you give to the Levites shall be the six cities of refuge, where you shall permit the manslayer to flee, and in addition to them you shall give forty-two cities. All the cities that you give to the Levites shall be forty-eight, with their pasturelands. And as for the cities that you shall give from the possession of the people of Israel, from the larger tribes you shall take many, and from the smaller tribes you shall take few; each, in proportion to the inheritance that it inherits, shall give of its cities to the Levites.”
The cities of the priests and Levites were not only to accommodate them, but to place them, as religious teachers, in several parts of the land. For though the typical service of the tabernacle or temple was only in one place, the preaching of the word of God, and prayer and praise, were not thus confined. These cities were to be given out of each tribe. Each thus made a grateful acknowledgement to God. Each tribe had the benefit of the Levites dwelling amongst them, to teach them the knowledge of the Lord; thus no parts of the country were left to sit in darkness. The gospel provides that he who is taught in the word, should communicate to him that teaches, in all good things, Ga 6:6. We are to free God’s ministers from distracting cares, and to leave them at leisure for the duties of their station; so that they may be wholly employed therein, and avail themselves of every opportunity, by acts of kindness, to gain the good-will of the people, and to draw their attention. (Henry)
The Levites are to receive 48 cities with their surrounding land, six of which are to be ‘cities of refuge.’ The cities are to be contributed by each tribe in numbers proportionate to its size. (Cambridge)
And the Lord spake to Moses,…. After he had described the borders of the land, and given instructions about the division of it among the several tribes, and named the persons that should be concerned in parting and putting it into the possession of the Israelites, he makes a provision for the Levites.
