바이크라 (레위기) 1:8

בני אהרן הכהנים THE SONS OF AARON THE PRIESTS — i e. only as priests : when they are ministering in their priestly dignity; but if an ordinary priest officiates in the eight garments of the High Priest his service is invalid (Sifra, Vayikra Dibbura d'Nedavah, Chapter 5 9; Zevachim 18a). את הראש את הנתחים [AND THE PRIESTS … SHALL SET] THE PIECES, THE HEAD etc. [IN ORDER] — Since the head was not included in the law prescribing flaying (v. 6) as it was already as good as cut off by the act of slaughter, it therefore was necessary to enumerate it separately here since Scripture wishes every part of the animal to be put on the altar (cf. Sifra, Vayikra Dibbura d'Nedavah, Chapter 6 3; Chullin 27a). ואת הפדר AND THE FAT — Why is this mentioned separately (is it not included in the word הנתחים)? In order to teach you that he must bring it up on the altar together with the head, and that with it he must cover the throat of the animal (בית השחיטה, lit., the place where the act of slaughter was performed). This (covering the cut in the throat) was done in way of regard for God on high (Chullin 27a). אשר על המזבח WHICH IS UPON THE ALTAR — upon the altar: this implies that the logs of wood must not project beyond the woodpile (מערכה) (Sifra, Vayikra Dibbura d'Nedavah, Chapter 6 5).

וְעָרְכ֗וּ בְּנֵ֤י אַהֲרֹן֙ הַכֹּ֣הֲנִ֔ים אֵ֚ת הַנְּתָחִ֔ים אֶת־הָרֹ֖אשׁ וְאֶת־הַפָּ֑דֶר עַל־הָעֵצִים֙ אֲשֶׁ֣ר עַל־הָאֵ֔שׁ אֲשֶׁ֖ר עַל־הַמִּזְבֵּֽחַ׃

and the priests, Aharon’s sons, shall lay the parts, the head, and the fat, in order upon the wood that is on the fire which is upon the altar:
