3 Then Moses said unto Aaron, This is it that the Lord spake, saying, I will be sanctified in them that come nigh me, and before all the people I will be glorified. And Aaron held his peace.
4 And Moses called Mishael and Elzaphan, the sons of Uzziel the uncle of Aaron, and said unto them, Come near, carry your brethren from before the sanctuary out of the camp.
5 So they went near, and carried them in their coats out of the camp; as Moses had said.
6 And Moses said unto Aaron, and unto Eleazar and unto Ithamar, his sons, Uncover not your heads, neither rend your clothes; lest ye die, and lest wrath come upon all the people: but let your brethren, the whole house of Israel, bewail the burning which the Lord hath kindled.
7 And ye shall not go out from the door of the tabernacle of the congregation, lest ye die: for the anointing oil of the Lord is upon you. And they did according to the word of Moses.
The loss of his sons must have been a terrible blow to Aaron, but wisely he accepted the Lord’s judgment and held his peace. The totality of God’s path is absolute. On the one hand, no one is forbidden from coming to Him, but also no one is excused from betraying Him. It does not matter our status, God’s laws apply just as much to the king as to the beggar, as much to the priest as to the pagan.
No doubt the weight of this reality rested on the minds of Aaron and his two surviving sons as Moses forbade them from performing the traditional rituals of mourning. It seems as though Nadab and Abihu’s betrayal took place sometime during the initiation process. The priests were staying in the sanctuary day and night for a full week, so there was plenty of opportunity for it to have occurred.
It was imperative that Aaron and his sons not abandon their purification process partway through. They were still acting in their divine office; they were still standing in as representatives of God, and it would not do for the representative of God to bewail the judgment of God. That would be contradictory.
Even so, Moses assured them that the people of Israel would mourn for them. Just as the priests must stand as representatives of God to the people, the people would stand as representatives of the brokenhearted men to God.
Aaron and his sons accepted their solemn duty, and “did according to the word of Moses.” Each of them would fulfill this initiation, commit themselves sincerely, and live out the rest of their lives without causing such a breach as Nadab and Abihu had done.
