Which the children of Aaron, [being] of the families of the Kohathites,…. Who descending from Kohath, in the line of Aaron, were priests:
[who were] of the children of Levi, had; they were Levites, as descending from Levi, but were priests also, as being of the stock of Aaron, and the cities hereafter mentioned in the said tribe fell to their portion:
for theirs was the first lot; for being of the line of Aaron, and priests, they had the honour and privilege to have the first lot drawn for them, and out of the tribe for which the first lot was also drawn, the tribe of Judah; here they had their cities allotted them, for a reason before given.

Ver. 10-18. Which the Kohathites had; for their’s was the first lot Thus the Levite priests had for their part, as well in Simeon as in Judah, Hebron, excepting the country about it, which was already given to Caleb; ch. Jos 14:14. Libnah, Jattir, Eshtemoa, Holon, Debir, Ain, Juttah, and Beth-shemesh; and in the tribe of Benjamin, Gibeon, Geba, Anathoth, and Almon, all which cities have been mentioned before, particularly in ch. 15: Of these, as well as of the other cities assigned to the Levites, we have a catalogue in 1 Chronicles 6 but that is imperfect; and, it should be observed, that the cities there are sometimes named otherwise than here. This may proceed from two causes: first, that, it being impracticable, to take some of these cities from the Canaanites, there was a necessity of substituting others in their stead, which are named in the list inserted 1 Chronicles 6. Secondly, that some of these cities had probably two names, or else had changed their names in the course of time. We also meet with differences in the names of the cities which fell to the Levites, on reading them in the version of the LXX. The copies printed from the Alexandrian manuscript render the Hebrew with the utmost exactness; but several names are there omitted. On the contrary, the copies which follow the Vatican manuscript omit very few names of cities, but those are mostly disfigured, or wholly different.

21:10 Which the children of {d} Aaron, [being] of the families of the Kohathites, [who were] of the children of Levi, had: for theirs was the first lot.
(d) For Aaron came from Kohath, and therefore the priests office remained in that family.
