What are the connotations of "ve'Nikdash bi'Chevodi"?
Rashi #1: It means that the Mishkan will become sanctified when Hashem comes to rest His Shechinah in it.
Rashi #2 (citing a Midrash) and Targum Yonason: Reading "bi'Chevodi" as "bi'Mechubadai", it means that Hashem would be sanctified by His honored ones (a hint to the death of Nadav and Avihu), 1 (though what the hint was referring to was not disclosed until they actually died - Rashi).
Rashbam: It means that Hashem will appear to Yisrael when the Mishkan is finally set-up, when fire will descend to consume the Korbanos. 2
Oznayim la'Torah: It is the fact that the Ohel Mo'el serves as a place where the Shechinah rests to speak with Yisrael that sanctifies it - more than the Korbanos that they bring there. 3
Rashi: As the Torah indicates later in Shemini, Vayikra 10:3, when Moshe informs Aharon that Hashem had predicted their death - though he did not know to whom it referred until they actually died, at which point Moshe said to Aharon 'Aharon my brother, your sons died in order to sanctify Hakadosh-Baruch-Hu's Name!' (Zevachim, 116b).
Rashbam: As the Torah describes in Shemini, Vayikra, 9:23 & 24.
Oznayim la'Torah: Just as the throne-room is more esteemed than the room where the king's servants perform the king;s service.
