Why does the Torah write "ve'ha'Chonim lifnei ha'Mishkan" and not 'Yachanu' (in the command form [Sifsei Chachamim]):
Rashi: This hints
at the fact that Degel Machaneh Yehudah, who also encamped in the east, were neighbors of Moshe
- which explains why Yehudah, Yisachar and Zevulun were all great in Torah.
Based on the principle "Tov la'Tzadik, Tov li'Shecheino'.
Why is there a stroke between Moshe and Aharon and his sons?
Ba'al ha'Turim: To teach us that Moshe and Aharon and his sons encamped separately.
