Joshua 21:12

New Century Version

But the fields and the villages around Kiriath Arba had been given to Caleb son of Jephunneh.

See the chapter Copy

from the tribe of Judah, Caleb son of Jephunneh;

They gave them Kiriath Arba, also called Hebron, and all its pastures in the mountains of Judah. (Arba was the father of Anak.)

So they gave the city of Hebron to the descendants of Aaron (Hebron was a city of safety). They also gave them the towns of Libnah,

We had raided the southern area of the Kerethites, the land of Judah, and the southern area of Caleb. We burned Ziklag, as well.”
