Why does the Torah repeat here "Vayishma ha'Cana'ani... ", but does not finish the episode'?
Rashi: To teach us that what they heard was that Aharon died and that the Ananei Kavod had departed 1 - leading them to believe that they were now permitted to attack Yisrael.
Elef ha'Magen: Refer to 33:8:151:1. The Cana'ani thought that now that Aharon had died, the Avodah ceased and Yisrael had lost their Divine protection. 2
What is "ba'Negev" referring to?
Rashi (in Vayishlach Bereishis, 35:18): It is referring to Eretz Yisrael, which is in the south (of Aram Naharayim - Rashi). 1
See Rashi Ibid.: It is not clear however, why the Torah needs to insert "be'Negev" here, unless it is to inform us that the Cana'ani, king of Arad was living in the south of Eretz Cana'an?
Rashi (21:1) says that "Cana'ani Melech Arad" was Amalek. Why does the Torah refer to them as 'Cana'ani'?
