Joshua 21:10 Meaning and Commentary

Joshua 21:10

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.

Joshua 21:10 In-Context

8 So the Israelites allotted to the Levites these cities, together with their pasturelands, as the LORD had commanded through Moses.

9 From the tribes of Judah and Simeon, they designated these cities by name

10 to the descendants of Aaron from the Kohathite clans of the Levites, because the first lot fell to them:

11 They gave them Kiriath-arba (that is, Hebron), with its surrounding pasturelands, in the hill country of Judah. (Arba was the father of Anak.)

12 But they had given the fields and villages around the city to Caleb son of Jephunneh as his possession.
