2 Give orders to the children of Israel to give to the Levites, from the heritage which is theirs, towns for themselves, with land on the outskirts of the towns. 3 These towns are to be their living-places, with land round them for their cattle and their food and all their beasts, 4 Stretching from the wall of the towns a distance of a thousand cubits all round. 5 The measure of this space of land is to be two thousand cubits outside the town on the east, and two thousand cubits on the south and on the west and on the north, the town being in the middle. This space will be the outskirts of their towns. 6 And the towns which you give the Levites are to be the six safe places to which the taker of life may go in flight; and in addition you are to give them forty-two towns. 7 Forty-eight towns are to be given to the Levites, all with land round them.

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.
