Joshua 21:41

41.All the cities of the Levites, etc This passage more especially shows what I have already more than once adverted to, that the boundaries of the other tribes were not so confined as not to comprehend a far larger number of cities than is actually mentioned. It is perfectly well known that Levi was the least numerous of all the tribes. With what equity, then, could it have been allowed to expand itself over four times the space allowed to the tribe of Zebulun, which, though more populous, is mentioned as only possessing twelve cities. Only sixteen are enumerated as belonging to the tribe of Issachar, nineteen to the tribe of Naphtali, and twenty-two to the tribe of Asher. It would surely have been an unequal division to give the greater number of cities for habitation to the smaller population. Hence we infer, that not only the villages which are here set down as accessories of the cities were fit for habitation, but that other cities also, of which no mention is made, were included. In short, the extent of the lot of Levi makes it perfectly obvious how large and ample the territories of the other tribes must have been.
