Why is the 'Gimel' in "Ve'hisgalach" big?
Ba'al ha'Turim, Moshav Zekenim: It hints at the three people who need to shave all their hair [on their bodies, or for a Nazir, on his head] - a Nazir, 1 a Metzora and the Levi'im (when they were inaugurated). 2
Kidushin 30a says that this is the middle verse of the Torah. This is unlike our tradition! Daf Al ha'Daf (citing R. Y. Alter) - it is the middle of the verses with big letters. 3
What does the Pasuk mean when it writes "v'Es ha'Nesek Lo Yegale'ach"? There are no hairs in the Nesek!
Rashi citing Toras Kohanim: It means that the Kohen must leave two hairs at the extremity of the Nesek, so that it will be discernable should it spread during the seven days quarantine.
Ramban, Moshav Zekenim: It is a Lo Sa'aseh against shaving the skin of the Nesek. 1
Ramban, Moshav Zekenim: Because it causes hair to grow there.
