John Wesley on Joshua 21:41

Forty eight cities - Why hath this tribe, which was the least of all, more cities than any of them? First, it doth not appear that they had more: for though all the cities of the Levites be expressed, it is not so with the other tribes, but divers of their cities are omitted. Secondly, the Levites were confined to their cities and suburbs; the rest had large territories belonging to their cities, which also so they were in a capacity of improving, which the Levites were not; so that one of their cities might be more considerable than divers of the Levites. Thirdly, God, was pleased to deal liberally with his ministers, to put honour on those whom he foresaw many would be prone to despise; and, that being free from outward distractions, they might more entirely and fervently devote themselves to the service of God.
