Thirteen cities - This number is said to be too great for the single family of Aaron. But it appears 1 Chronicles 24 that the two surviving sons of Aaron, Eleazar and Ithamar, had together 24 sons, the heads of the priestly families. Since Aaron was 123 years old when he died Numbers 33:39, his sons' grandchildren and great grandchildren were no doubt living in the elapsing years of Joshua's course, and had to he provided with dwellings. They might altogether number several thousands. The "cities" of Canaan were for the most part small; as is manifest from the astonishing number of them in proportion to the area of the land, more particularly in the south, where the portion of the priests was situated. The priests or Levites would not occupy the whole of the dwellings in any city, nor all its "fields," nor necessarily and always all its "villages" (compare Joshua 21:12). Non-Levites, to whom the cultivation of their land, and other secular concerns, were entrusted, no doubt resided in the Levitical cities or their precincts. It appears, further, that several of the cities here enumerated were only wrested from the Canaanites at a later date.

Out of the tribe of Judah - Simeon, and - Benjamin, thirteen cities - These tribes furnished more habitations to the Levites in proportion than any of the other tribes, because they possessed a more extensive inheritance; and Moses had commanded, Numbers 35:8, From them that have many, ye shall give many; and from them that have few, ye shall give few: every one shall give of his cities unto the Levites, according to his inheritance. It is worthy of remark, that the principal part of this tribe, whose business was to minister at the sanctuary, which sanctuary was afterwards to be established in Jerusalem, had their appointment nearest to that city; so that they were always within reach of the sacred work which God had appointed them.

And the lot came out for the family of the Kohathites,.... The first lot that was drawn out of the pot or urn was for the descendants of Kohath, a son of Levi:

and the children of Aaron the priest, which were of the Levites; who descended from Amram, the eldest son of Kohath, and these were not only Levites, but priests: these

had by lot out of the tribe of Judah, and out of the tribe of Simeon,

and out of the tribe of Benjamin, thirteen cities; which are after mentioned by name; and as these were priests, whose business was to serve in the temple, and at the altar, the cities assigned them by the lot, were, by the wise disposal of divine Providence, ordered them out of those tribes which lay nearest to Jerusalem; the place God had chosen to put his name in, where the temple would be built, and the altars erected for sacrifices and incense.

Number of the cities which the different families of Levi received from each tribe. The tribe of Levi was divided into three branches, - The Gershonites, the Kohathites, and the Merarites (see Numbers 3 and Exodus 6:16-19). The Kohathites again were divided into the four families of Amram, Izhar, Hebron, and Uzziel (Exodus 6:18); and the family of Amram into two lines, consisting of the descendants of Moses and Aaron (Exodus 6:20). The priesthood was committed to the line of Aaron (Numbers 18:1-7); but the other descendants of Amram, i.e., the descendants of Moses, were placed on a par with the other descendants of Levi, and numbered among the simple Levites (Numbers 3; 1 Chronicles 6:1-7). The towns in which the different families of Levi were to dwell were determined by lot; but in all probability the towns which each tribe was to give up to them were selected first of all, so that the lot merely decided to which branch of the Levites each particular town was to belong.

Joshua 21:4

The first lot came out for the families of Kohath, and among these again for the sons of Aaron, i.e., the priests. They received thirteen towns from the tribes of Judah, Simeon, and Benjamin. "This did not happen by chance; but God, according to His wonderful counsel, placed them just in that situation which He had determined to select for His own temple" (Calvin).

And the lot came out for the families of the {b} Kohathites: and the children of Aaron the priest, which were of the Levites, had by lot out of the tribe of Judah, and out of the tribe of Simeon, and out of the tribe of Benjamin, {c} thirteen cities.

(b) He means those that were priests: for some were but Levites.

(c) Every tribe gave more or fewer cities according to the size of their inheritance, Nu 35:8.

21:4 Judah, Simeon, and Benjamin - Which three tribes were nearest the temple, where their business lay. Thirteen cities - For though the priests were now few enough for one city, yet respect was to be had to their succeeding numbers; this division being made for all future generations. And seeing the Levites might sell their houses until the Jubilee, Lev 25:33, much more might they let them; and therefore it is probable their cities were not long uninhabited, many being inclined to dwell with them by virtue of relations contracted with them; or out of respect to the service of God, and the good of their souls.

4-8. the lot came out for the families of the Kohathites-The Levites were divided into Kohathites, Gershonites, and Merarites. Among the former the family of Aaron were exclusively appointed to the priesthood, and all the rest were ranked in the common order of Levites. The first lot was drawn by the Kohathites; and the first of theirs again by the priests, to whom thirteen cities were granted, and ten to the rest of the Kohathites (Jos 21:5); thirteen to the Gershonites (Jos 21:6), and twelve to the Merarites (Jos 21:7).

21:1-8 The Levites waited till the other tribes were provided for, before they preferred their claim to Joshua. They build their claim upon a very good foundation; not their own merits or services, but the Divine precept. The maintenance of ministers is not a thing left merely to the will of the people, that they may let them starve if they please; they which preach the gospel should live by the gospel, and should live comfortably.
