Which Minchah is the Torah referring to?
Why does the Torah compare Zevach to Nesachim?
Menachos, 79a: To teach us that the Nesachim only become Kadosh with the Shechitah of the Zevach. 1
Bechoros, 17a: To teach us that, just as the Zevach has not changed, 2 so too, have the (smell of the) Nesachim not changed - by bending the vine over a fig-tree.
See Torah Temimah, note 109. It is not clear as to why the Chachamim do not make the same D'rashah regarding "Olah" and "Minchah"? Refer to 23:37:1:1*.
See Torah Temimah, note 110.
What are the implications of "D'var Yom be'Yomo"?
Rashi #1: With reference to the Musafim listed in Bamidbar 29:12 - 39, where the Torah prescribes a different Korban for each day of Sukos, including Shemini Atzeres, it implies that, if the Kohanim fail to bring the specified Musaf on any one day, they are not permitted to compensate by bringing it on the following day. 1
Rashi #3 (in Pesachim, 58a): 'Yom' implies after midday ? as opposed to 'Boker', which means in the morning. 2
Temurah, 14a: It implies that Musafin may be brought the entire day (up until sunset).
See Torah Temimah, note 112. They do however, remain obligated to bring the Nesachim, if they failed to bring them on that day - See Torah Temimah, citing Temurah, 14a and note 113.
Rashi (Ibid.): Since the Torah never uses the word 'Boker' in connection with the Musaf, only 'Yom', and, as the Gemara states in Yoma, 34a ? 'Boker' implies earlier, 'Yom', later.
