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

Numbers 3:27
From Kohath came the clans of the Amramites, the Izharites, the Hebronites, and the Uzzielites; these were the clans of the Kohathites.

Joshua 21:9
From the tribes of Judah and Simeon, they designated these cities by name

Joshua 21:11
They gave them Kiriath-arba (that is, Hebron), with its surrounding pasturelands, in the hill country of Judah. (Arba was the father of Anak.)

1 Chronicles 6:54
Now these were the territories assigned to the descendants of Aaron from the Kohathite clan for their settlements, because the first lot fell to them:

Which the children of Aaron, being of the families of the Kohathites, who were of the children of Levi, had: for theirs was the first lot.
