QUESTIONS ON RASHI

Gur Aryeh: Midbar Kadesh is the general name for as vast area of desert, which included both Midbar Paran and Midbar Tzin, as well as a specific place called Kadesh-Barnea. 1
Gur Aryeh: The thirty-eight years wandering in the desert were spent half within Midbar Kadesh, and half wandering in its vicinity and then returning to Kadesh (Rashi to Devarim 1:46, based on Seder Olam). Therefore, they were still there in the 40th year. See also Tosfos to Shabbos 89a DH Midbar.

Gur Aryeh #1: "Pilug Dina" means "the splitting of judgment" between the exonerated and guilty parties. We interpret "Ein Mishpat" as, "l'Ayein b'Mishpat," "to look [thoroughly] into judgment."
Gur Aryeh #2 (citing Ramban): "Pilug Dina" means "the depth of judgment," as in, "getting to the depths of the matter." "Ein Mishpat" is an analogy to a spring that emerges from the deep.
Rashi writes: "The fields of the Amalekim - Amalek had not yet been born; the Torah calls the location by its future name." Ramban asks
