Regarding the Korban that the Kohen Gadol brings on the day of his inauguration, to whom does "Banav" refer?
Rashi and Rashbam #2 (citing Chazal): It refers to the Kohanim Hedyotim (on the day of their inauguration exclusively). 1
Rashbam #1: It refers to the Kohanim Gedolim who succeed Aharon.
Because the Kohanim Gedolim who take over after Aharon are specifically mentioned in Pasuk 15 (Toras Kohanim).
How much is an Eifah?
Targum Yonasan: One Eifah = 3 Sa'ah. 1
3 Sa'ah = 18 Kabin = 72 Lugin = 432 k'Beitzim. Consequently, 1/ 10 Eifah = 43.2 egg-volumes. This is the size of a dough from which one must separate Chalah.
What are the implications of the word "Tamid"?
Rashi: The Kohen Gadol is obligated to bring this Korban every day.
