2 "Command the children of Israel that they give the Levites cities to dwell in from the inheritance of their possession, and you shall also give the Levites common-land around the cities. 3 They shall have the cities to dwell in; and their common-land shall be for their cattle, for their herds, and for all their animals. 4 The common-land of the cities which you shall give the Levites shall extend from the wall of the city outward a thousand cubits all around. 5 And you shall measure outside the city on the east side two thousand cubits, on the south side two thousand cubits, on the west side two thousand cubits, and on the north side two thousand cubits. The city shall be in the middle. This shall belong to them as common-land for the cities. 6 Now among the cities which you will give to the Levites you shall appoint six cities of refuge, to which a manslayer may flee. And to these you shall add forty-two cities. 7 So all the cities you will give to the Levites shall be forty-eight; these you shall give with their common-land.

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, Galatians 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.
