So the Israelites chose some cities to be called cities of safety. These are the cities: Kedesh in Galilee in the hill country of Naphtali; Shechem in the hill country of Ephraim; Kiriath Arba (Hebron) in the hill country of Judah;
Six of those cities will be cities of safety. If a person accidentally kills someone, that person can run to those towns for safety. In addition to those six cities, you will also give 42 more cities to the Levites.
So the Edomites broke away from the rule of Judah. And they have been free from the rule of Judah until today. At the same time Libnah also broke away from Judah’s rule.
