2 Command the children of Israel, that of the inheritance of their possession they give unto the Levites cities to dwell in; and a suburb for the cities round about them shall ye give unto the Levites. 3 And the cities shall they have to dwell in, and their suburbs shall be for their cattle, and for their goods, and for all their beasts. 4 And the suburbs of the cities that ye shall give unto the Levites shall be from the walls of the city outward, a thousand cubits round about. 5 And ye shall measure, without the city, the east side two thousand cubits, and the south side two thousand cubits, and the west side two thousand cubits, and the north side two thousand cubits, and the city shall be in the midst: they shall have this as suburbs of the cities.

Commentary on Numbers 35:1-8
(Read Numbers 35:1-8)
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.
