Whereas the whole house of Israel was bidden to bewail the death of Nadab and Abihu, for "the death of a pious man is greater misfortune to Israel than the Temple's burning to ashes,"-Aaron and his sons, on the other hand, were permitted to take no share in the mourning, and Moses bade them eat of the parts of the offering due them, as if nothing had happened. Now when Moses saw that Aaron had burnt to ashes one of the three sin offerings that were offered on that day, without himself or his sons having partaken of it, his wrath was kindled against his brother, but in consideration of Aaron's age and his office Moses addressed his violent words not to Aaron himself, but to his sons.
He reproached them with having offended against God's commandment in burning one sin offering and eating of the other two. He asked them, besides, if they were not wise enough to profit by the example of their deceased brothers, who paid for their arbitrary actions with their lives, particularly since they also had been doomed to death, and owed their lived only to his prayer, which had power to preserve for their father half the number of sons.
Moses' reproof, however, was unjustified, for Aaron and his sons had done what the statutes required, but Moses had on this occasion, as on two others, owing to his wrath, forgotten the laws which he himself had taught Israel. Hence Aaron opposed him decidedly and pointed out his error to him. Moses, far from taking Aaron's reprimand amiss, caused a herald to make an announcement throughout the camp: "I have falsely interpreted the law, and Aaron, my brother, has corrected me.
Eleazar and Ithaman also knew the law, but were silent out of consideration for me." As a reward for their considerateness, God thereupon revealed important laws to Moses with a special injunction to tell them to Aaron as well as to Eleazar and Ithamar.
