Rashi writes that Eretz Yisrael is 400 Parsah by 400 Parsah. A person can walk 10 Parsah per day. It should take 40 days to walk in each of the four directions. How wer the spies able to returne in 40 days?
Rashi: Hashem, in His mercy, anticipating that He would decree that Yisrael remain in the desert "a year for each day", hastened their return. 1
Rashi writes that Eretz Yisrael is 400 Parsah by 400 Parsah; One who announces a Metzi'ah in Yerushalayim, waits for the loser to return three days to his house
Moshav Zekenim (24): The settled part of Eretz Yisrael was close to Yerushalayim. With vineyards and forests, the land spanned 400 Parsah. Caravans were frequent, so they could travel day and night (double the normal amount). 1 .
It follows that everyone lived within six days of Yerushalayim, and most of Eretz Yisrael was only vineyards and forests. It says (Bereishis 49:13) that Zevulun will dwell on the sea shore, and we know that they sailed for business. Did they all live at least 14 days journey from the shore?! Ako is on the sea shore (Nedarim 30a-b); R. Meir rules that Ako is like Eretz Yisrael for Gitin (Gitin 1:2) Surely Yisraelim dwelled there! Some answer that people used to travel quicker; Bava Metzi'a 28a connotes unlike this. Eretz Yisrael is called Eretz Tzvi, for it expands according to its inhabitants (Gitin 57a). She'elas Ya'avetz 1:127 brings from Chesed l'Avraham (Mayan 3, Nehar 3) that it shrunk to 100 Parsah by 100. Alternatively, 400 Parsah is with the lands of Kini, Kenizi and Kadmoni, which will be added in the future. (Megilah 3a implies that Eretz Yisrael already was 400 Parsah by 400 Parsah! Refer to 13:25:152:1,2 and the note there.
Rashi writes that Eretz Yisrael is 400 Parsah by 400 Parsah; What is his source?
Megilah 3a, Bava Kama 82b, Menachos 64b: Eretz Yisrael shook 400 Parsah by 400 Parsah. 1
Zohar 3 Kedoshim 84a: Eretz Yisrael is 400 Parsah by 400 Parsah. .
Rashi writes that the Meraglim had Kefitzas ha'Derech. Sanhedrin 95a says that three had Kefitzas ha'Derech, and the Meraglim are not among them!
Riva: The Gemara lists only Tzadikim; [most of] the Meraglim were Resha'im.
