Why did Aharon wave the Levi'im?
"Veheinif Aharon es ha'Levi'im ? ". Why does the Torah mention Tenufah three times in this Parshah - in the current Pasuk and in Pesukim 13 & 15?
Rashi and R. Bachye: Once regarding the B'nei K'has - "Vehayu La'avod Avodas Hashem" 1 (in the current Pasuk). Once regarding the B'nei Gershon - "Tenufah la'Hashem" 2 (in Pasuk 13); and once regarding the B'nei Merari - "Veheinafta osam Tenufah" 3 (in Pasuk 15). 4
Rashbam: The Torah repeats "Veheinafta osam Tenufah" in Pasuk 15, to inform Moshe that he should wave the Levi'im after Aharon. 5
Rashi: Because they carried the holy vessels - the Aron, the Shulchan ? '.
Rashi: Because they too, transported the curtains and the hooks, which were also Kodesh because they were visible in the Kodesh Kodshim.
R. Bachye: Since they carried the planks, and the copper bolts, pillars and sockets - which were all not Kodesh.
Oznayim la'Torah: This was necessary due to the two types of Avodah performed by the Levi'im - 1. Avodos that only the Levi'im may perform - see Oznayim ls'Torah), into which Aharon inaugurated them; 2. Avodos that a Kohen and even a Zar are permitted to perform - such as Shechting and skinning, into which Moshe inaugurated them
