‘ And to the children of Aaron the priest they gave Hebron with her suburbs, the city of refuge for the manslayer, and Libnah with her suburbs, and Jattir with her suburbs, and Eshtemoa with her suburbs, and Holon with her suburbs, and Debir with her suburbs, and Ain with her suburbs, and Juttah with her suburbs, and Beth-shemesh with her suburbs. Nine cities out of those two tribes.'
The repetition of Joshua 21:13 compared with Joshua 21:11 suggests that here the writer is copying an official list and therefore includes Hebron again as part of that list. The repetition was also necessary to bring out that Hebron was a city of refuge. For Libnah see Joshua 10:29, for jos Jattir Joshua 15:48, for Eshtemoa Joshua 15:50, for Holon Joshua 15:51, for Debir Joshua 10:38; Joshua 15:15, for Ain Joshua 19:7, for Juttah Joshua 15:55, for Beth-shemesh Joshua 15:10. Note how the two tribes of Judah and Simeon are spoken of almost as one. There is no other example in the chapter of two tribes being linked in this way. Only Ain was from Simeon directly.
