Rashi on TanakhLeviticus 8

Take Aharon. This section was said seven days before the setting up of the Tabernacle, for there is no earlier and later [= chronological order] in the Torah.

Take Aharon, take him with [kind] words and draw him [to you].

And the bull [for] the sin-offering, etc. These are mentioned in the section [which contains] the commands of the installation-sacrifices [in the sidro] of Ve’atoh Tetzaveh. Now, on the first day of the installation-sacrifices He repeated [the commands] to urge him on during the [actual] fulfillment [of the command.

Assemble [the entire congregation] at the entrance of the Tent of Meeting. This is one of the places [in] which a smaller [area] held a larger [number].

This is the edict — the things which you will see that I do before you [= in your sight] God commanded me to do; you should not say that [it is] for my honor and my brother’s [= Aharon’s] honor [that] I do them. I explained this whole matter [of the installation] [the sidra of] Ve’atoh Tetzaveh.

The urim, the letters of the שֵׁם הַמְפוֹרָשׁ .

He placed on the. . .turban. Greenish-blue woolen cords which were set in the diadem he placed on the turban — thus the diadem was suspended by the turban.

He sprinkled some of it on the altar. I do not know where he was commanded regarding these sprinklings.

He poured, he anointed. At first he poured [some oil] on his head, and after that he placed [some] between his eyebrows, and drew [the oil with] his finger [along] either side.

He tied, an expression [denoting] tying.

He purified the altar, he cleaned and purified it from any strangeness [so that it might] enter into [a state of] holiness.

And sanctified it with this service

to atone upon it — from now on all the atonements [might be brought].

[The lobe of] the liver — aside from the liver, for he would take a little of the liver with it.

The ram for the installation-offering, the ram of the wholeness-offering, for “installation” is an expression of “wholeness,” for they fulfill and complete the kohanim in their priesthood.

Oil-bread, that is the scalded dough in which he would use much oil, [to a total of oil] equal to that added to the] loaves and wafers [together]; so it is explained in [Maseches] Menochos.

He burned them on the altar. Moshe performed [the Temple service] all seven days of installation in a white garment.

In addition to the burnt-offering, after the burnt-offering; and we do not find a thigh of a peace-offering brought [= burnt] in any place but this [= offering].

Adonoy commanded him to do, all seven days. And our Rabbis expounded: To do, this [refers] to the ritual of the Red Heifer, to bring about atonement, this [refers] to the ritual of Yom Kippur, and to teach that the Kohein Godol requires seclusion seven days before Yom Kippur, and similarly the kohein who burns the Heifer.

And you will not die, thus, if you do not do so, you are liable to [the] death [penalty].

Aharon and his sons fulfilled, to tell their praise, that they did not deviate to the right or left.
