Where are Kadesh Barne'a and Azah?
Rashi: They are in the south, from east to west, but he did not conquer all the way to the sea. From Azah until the sea remained - "ha'Aretz ha'Nish'ares... ha'Azasi veha'Ashdodi..." (13:2,3).
Malbim: They are in the south, from east to west. This is the border of Yehudah.
Goshen is in Egypt (Bereishis 47:6)!
Radak: This is a different Goshen. Malbim - it is in Yehudah's portion (15:51).
Radak (11:16, citing a Midrash), Da'as Zekenim (Bereishis 46:29): It is Goshen of Egypt. It was swallowed among cities of Yisrael. "Va'Ya'al... Goshnah" (Bereishis 46:29) - it is rising towards Eretz Yisrael. Since Yehudah was his father's Shali'ach to go there in front of him (46:28), he merited that Goshen, which is a good land 1 , be in his portion.
Rashi brought (from Kesuvos 112a; refer to Bamidbar 13:22:2:1) that the worst part of Eretz Kena'an was far better than the best part of Egypt! Perhaps after it became part of Eretz Yisrael, it improved drastically. (PF)

Malbim: It is in Binyamin's portion.
