Leviticus 10:16

שעיר החטאת THE GOAT OF THE SIN OFFERING — This was the goat of the additonal offerings of the New Moon. Three goats for sin-offerings had been sacrificed that day: a goat of the kids prescribed for the installation ceremony (see Leviticus 9:3), and the goat brought by Nachshon as a free-will offering, and the goat for the New Moon. Of all these, this last alone had been burnt, and the Sages of Israel differ in their opinions regarding the matter. Some say that it was on account of some uncleanness (unclean thing) which had touched it that it was burnt, whilst others say that it had been burnt on account of the state of mourning in which Aaron’s sons were, for it was a holy sacrifice ordained for all generations and was not of an exceptional character whilst in the case of the occasional holy sacrifices (the two other goats) they relied on Moses’ statement when he said in respect to the occasional meal-offering (v. 12), “and eat it as unleavened cakes”, although you are Onanim, and they took this to apply also to those goats which were also of an occasional character (Sifra, Shemini, Chapter 2 8-10; Zevachim 101a). דרש דרש [MOSES] DILIGENTLY ENQUIRED ABOUT — The repetition of the word implies that he made two enquiries: why has this (the goat for the New Moon) been burnt and why have these other goats been eaten? — Thus it is stated in Torath Cohanim (Sifra, Shemini, Chapter 2 2). על אלעזר ועל איתמר [HE WAS ANGRY] WITH ELEAZAR AND ITHAMAR — Out of the respect due to Aaron he turned towards his sons and showed himself angry with them instead of with Aaron (Sifra, Shemini, Chapter 2 3). לאמר SAYING (i. e. that they should say or speak) — He said to them, “Give me replies to my questions” (Sifra, Shemini, Chapter 2).

And Moshe diligently sought the goat of the sin offering, and, behold, it was burnt: and he was angry with El῾azar and Itamar, the sons of Aharon that were left alive, saying.
