John Gill's Bible Commentary Ver. 7. So all the cities which ye shall give to the Levites shall be forty eight cities , etc.] Of these forty eight cities, their names, and what tribes they were in, and which of them were particularly cities of refuge, an account is given in ( Joshua 21:10-37): them shall ye give, with their suburbs ; according to the dimensions before prescribed.
Matthew Henry Commentary
Verses 1-8 - The cities of the priests and Levites were not only to accommodat them, but to place them, as religious teachers, in several parts of the land. For though the typical service of the tabernacle or temple wa only in one place, the preaching of the word of God, and prayer an praise, were not thus confined. These cities were to be given out of each tribe. Each thus made a grateful acknowledgement to God. Eac tribe had the benefit of the Levites dwelling amongst them, to teac them the knowledge of the Lord; thus no parts of the country were lef 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, God 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 ma be wholly employed therein, and avail themselves of every opportunity by acts of kindness, to gain the good-will of the people, and to dra their attention.
