The Sin of Nadab and Abihu
(Numbers 3:1-4)
1Now Aaron’s sons Nadab and Abihu  took their censers, put fire in them and added incense,  and offered unauthorized fire before the LORD,  contrary to His command.  
2So fire came out from the presence of the LORD and consumed them, and they died in the presence of the LORD.
3Then Moses said to Aaron, “This is what the LORD meant when He said: ‘To those who come near Me I will show My holiness, and in the sight of all the people I will reveal My glory.’ ” But Aaron remained silent.
4Moses summoned  Mishael  and Elzaphan, sons of Aaron’s uncle Uzziel, and said to them, “Come here; carry  the bodies of your cousins  outside the camp, away from the front of the sanctuary.”  
5So they came forward and carried them, still in their tunics,  outside the camp, as Moses had directed. 
6Then Moses said to Aaron and his sons Eleazar and Ithamar, “Do not let your hair become disheveled and do not tear your garments, or else you will die, and the LORD will be angry with the whole congregation. But your brothers, the whole house of Israel, may mourn on account of  the fire that the LORD has ignited. 
7You shall not go outside the entrance to the Tent of Meeting, or you will die, for the LORD’s anointing oil is on you.” So they did as Moses instructed.
Restrictions for Priests
8Then the LORD said to Aaron,  
9“You and your sons  are not to drink wine or strong drink when you enter  the Tent of Meeting, or else you will die; this is a permanent statute for the generations to come. 
10You must distinguish between the holy  and the common, between the clean and the unclean,  
11so that you may teach  the Israelites   all the statutes that the LORD has given them through Moses.”
12And Moses said to Aaron  and his remaining sons, Eleazar  and Ithamar, “Take  the grain offering that remains from the offerings made by fire to the LORD and eat it without leaven beside the altar, because it is most holy. 
13You shall eat  it in a holy place, because it is your share  and your sons’ share of the offerings made by fire to the LORD; for this is what I have been commanded. 
14And you and your sons and daughters  may eat the breast of the wave offering  and the thigh of the contribution in a ceremonially clean place, because these portions  have been assigned to you and your children  from the peace offerings of the sons of Israel. 
15They are to bring the thigh of the contribution and the breast of the wave offering, together with the fat portions of the offerings made by fire, to wave as a wave offering before the LORD. It will belong permanently to  you and your children,   as the LORD has commanded.”
16Later, Moses searched carefully for the goat of the sin offering, and behold, it had been burned up. He was angry with Eleazar  and Ithamar, Aaron’s remaining sons, and asked, 
17“Why didn’t you eat  the sin offering in the holy place? For it  is most holy; it was given to you to take away  the guilt of the congregation by making atonement for them before the LORD. 
18Since its blood  was not brought  inside the holy place, you should have eaten   it in the sanctuary area, as I commanded.” 
19But Aaron replied to Moses, “Behold, this very day they presented  their sin offering  and their burnt offering before the LORD. Since these things have happened to me,  if I had eaten the sin offering today, would it have been acceptable in the sight of the LORD?” 
20And when Moses heard this explanation, he was satisfied.
