Who is "Ish Elokim"?
Rashi (from Midrash Shmuel 8:1: It is Elkanah. Radak (from Seder Olam) - he was among the 48 Nevi'im who prophesized for Yisrael (Megilah 14a). 1
Malbim: It could not be Pinchas, for this affects him (to veer Kehunah [Gedolah] from Itamar's house to the house of Elazar (Pinchas' father).
Why does it say "ha'Niglo Nigleisi"?
Rashi: Did you know that I gave this greatness to Aharon? 1
Radak: Niglo is Makor (like an infinitive), like "Nish'ol Nish'al David" (20:28).
Why is there the prefix Hei in "ha'Niglo"?
Radak #1: This shows astonishment. My father says that it is connected to the end of the matter - did I choose him so [his descendants] will trample rebuff My Korbanos?!
Radak #2: This shows the truth of the matter, like "ha'Ratzachta v'Gam Yarashta" (Melachim 1 21:19). However, my father explained that also there, it is astonishment.
Radak #3: This begins the request to hear an answer, even though it is known, like "Ei Hevel Achicha", "va'Yomer Lo Ayeka", Mah Zeh b'Yadecha", "Mah Lecha Po Eliyahu", "Mah Lecha ha'Yam" (Bereishis 4:9, 3:9, Melachim 1 19:9, Tehilim 114:4. A) elsewhere, Hei introduces such a question - "ha'Ratzachta v'Fam Yarashta", "ha'Min ha'Sela ha'Zeh" (Bamidbar 20:10), "ha'Ra'isa Ki Nichna Achav" (Melachim 1 21:29).
To whom does "Beis Avicha" refer?
Rashi (from Tanchuma Shemos 27): It is Aharon. We learn from here that Aharon prophesized in Egypt. It was (Yechezkel 20:7) "va'Omer Aleihem Ish Shikutzei Einav Hashlichu uv'Gillei Mitzrayim Al Titama'u."
Radak: It is Moshe and Aharon.
Why did he mention "l'Beis Pharaoh"?
Radak citing Targum Yonasan: They were enslaved to Beis Pharaoh.
Malbim: Pharaoh had Kohanim, but they were not Kohanim of Yisrael or of Hashem. I chose Kohanim for Yisrael, to be intermediaries between Yisrael and Me!
