Joshua 21:3

Gave, by lot, ver. 4, &c. (Menochius) --- Whether any changes were afterwards made, to grant more or less, in proportion to the numbers of the four families, (as seems to have been done with regard to the other tribes) or the cities were specified in four parcels, and the priests received the first lot, the text does not explain. (Calmet) --- It is also uncertain what right the Levites had to these 48 cities. Some say that they had only the use of them, while others maintain that the cities were their property entirely, so that no other could live there without their consent. They could sell the houses, which returned to them in the year of the jubilee, if not redeemed before; but the suburbs were a common property of all the Levites, and could not be sold by any, Leviticus xxv. The cities, therefore, belonged to God, and he abandoned the property to his ministers. Other people might live among them, as they were not debarred from choosing their habitation in places which were not originally allotted to them. Thus we find that Gabaa was chiefly people by the tribe of Benjamin, when the outrage was offered to the Levite's wife, and no blame attached to the latter, Judges xix. Saul and his family were of the same town, though it belonged to the Levites, and David kept his court at Hebron, a sacerdotal city, for the first seven years of his reign. (Calmet) --- Here also Caleb had probably resided, chap. xiv. 14. The priests and Levites were not indeed at this time sufficiently numerous to people all these cities; and Calmet supposes that they only received as many houses as they might occupy, being supplied with more by the magistrates as their numbers increased. But might not they let the houses, which they did not want to occupy, and receive the profits, so as to take possession of them when they had occasion? Were these 48 cities, which were the only part of the land to which the Levites had any claim, too many or too rich to compensate the labours of this most deserving tribe? It seems, therefore, unnecessary to call in the aid or interference of the magistrate, except any person were so bold as to refuse to give up what the law had so positively assigned to the Levites. Their rights were as well defined as those of any of the other tribes. (Haydock) --- The land beyond the suburbs, was cultivated by the proprietors, who might either live in the town or country. Many of the priests and Levites chose to reside near the tabernacle, as Moses had encouraged them to do, Deuteronomy xviii. 6. Thus Nobe became a sacerdotal city; (1 Kings xxi. 1,) and after the temple was built, Jerusalem and its environs were the places of abode for most of the priests. (Calmet)
