Joshua 21:13

Thus they gave to the children of Aaron the priest
The families of the Kohathites, that part of them which descended from him, and were priests: Hebron with her suburbs, [to be] a city of refuge for the slayer;
that had slain a person unawares, and without design; see on ( Joshua 20:3 Joshua 20:7 ) ; and Libnah with her suburbs;
a royal city, of which see ( Joshua 10:29 Joshua 10:30 ) .
