What is the significance of the word "Paroches ha'Eidus?
Rashi #1: It refers to the Luchos, over which the Paroches protected and which the Torah describes as "Luchos ha'Eidus". 1
Rashi #2 (citing Shabbos, 22b): It refers to the Ner Ma'aravi. It was testimony [that the Shechinah is among Yisrael. It had the same amount of oil as the other six lamps, and it was always the last to go out, even though it was the first lit. 2
What are the ramifications of "Ya'aroch oso Aharon me'Erev ad Boker"?
Rashi: It implies that one should place sufficient oil, to burn the entire night, which Chazal assessed as half a Log in each lamp. 1
How will we reconcile the Pasuk here, which names Aharon (the Kohen Gadol) as the sole kindler of the Menorah, with Shemos 27:21, which writes "Aharon and his sons"?
Seforno: Even though all Kohanim are eligible to kindle the lights and to burn the Ketores, throughout Yisrael's stay in the desert, it was befitting for the Kohen Gadol to perform them 1 , because the Shechinah dwelt there every day 2 like it was destined to subsequently do on Yom Kipur. 3
Moshav Zekenim: Aharon would not let his sons go inside without him, after the death of Nadav and Avihu. However, he could go in alone.
How can the Menorah be lit "Tamid"? When they are Meitiv the Ner Ma'aravi (replace the old wick and put in oil), nothing is lit!
Moshav Zekenim #1: He would light a different Ner [from the Ner Ma'aravi] before extinguishing the Ner Ma'aravi to be Meitiv it.
Moshav Zekenim: He put a new wick in the Ner Ma'aravi while the Ner Ma'aravi was lit, and it ignited from the old wick (or he lit the new wick from the old wick, put the new burning wick into the Ner Ma'aravi) before he removed the old one.
Our verse implies that they lit the Menorah every day. Midrash Yelamdenu says that it burned from Rosh Hashanah to Rosh Hashanah!
Moshav Zekenim: Our verse discusses according to nature, if there is no miracle.
Why does it say here "Tamid", and in Tetzaveh it does not say Tamid?
