Leviticus 10:12

הנותרים WHO WERE LEFT from death. This teaches us that upon them, also, death had been pronounced in punishment for the sin of the golden calf. This is what is meant by the words (Deuteronomy 9:20) “And with Aaron the Lord was very angry to destroy him”, for the expression “destruction” means the extirpation of offspring, as it is said (Amos 2:9) “And I destroyed its fruit above”. Moses’ prayer, however, made half the sentence of none effect, (so that only two of Aaron’s four sons died) as it is said (Deuteronomy 9:20) “And I prayed also on behalf of Aaron at that time” (cf. Rashi on that passage). קחו את המנחה TAKE THE MEAL OFFERING, although ye are אוננים and the holy things are forbidden to an אונן (Zevachim 101a). את המנחה THE MEAL-OFFERING — This was the meal-offering prescribed for the eighth day of the installation ceremony and the meal-offering of Nachshon (Numbers 7:13; cf.

Leviticus 6:9)? Since, however, this (the meal-offering prescribed for the installation ceremony) was a communal meal-offering (cf. Leviticus 9:3—4) and an occasional meal-offering and nothing similar to it had been commanded for future generations and it was therefore possible that the regulations relating to meal-offerings in general did not apply, it was necessary expressly to set forth in respect of it the law already laid down for other meal-offerings (Sifra, Shemini, Chapter 1 4).

And Moshe spoke to Aharon, and to El῾azar and to Itamar, his sons that were left, Take the meal offering that remains of the offerings of the Lord made by fire, and eat it without leaven beside the altar: for it is most holy:
