In Leviticus, there is only one occasion where God speaks directly to Aaron. (HT Dr. John Kleinig.) It is when he gives the directive regarding the duties of the priests. As we continue to discuss our Life Together(tm) on the good ship Missouri, it is not a bad idea to remind ourselves of what it is that pastors do. (Spoiler Alert: Teach people, distinguish clean from unclean.) This is important work, and directly related to the task of Koinonia. But instead of me going on, here is what God tells Aaron, and a few context(tm) verses:
Now Nadab and Abihu, the sons of Aaron, each took his censer and put fire in it and laid incense on it and offered unauthorized[a] fire before the Lord, which he had not commanded them. 2 And fire came out from before the Lord and consumed them, and they died before the Lord. 3 Then Moses said to Aaron, “This is what the Lord has said: ‘Amongthose who are near me I will be sanctified, 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 to them, “Come near; carry your brothers away from the front of the sanctuary and out of the camp.” 5 So they came near and carried them in their coats out of the camp, as Moses had said. 6 And Moses said to Aaron and to Eleazar and Ithamar his sons, “Do not let the hair of your heads hang loose, and do not tear your clothes, lest you die, and wrath come upon all the congregation; but let your brothers, the whole house of Israel, bewail the burning that the Lord has kindled. 7 And do not go outside the entrance of the tent of meeting, lest you die, for the anointing oil of the Lord is upon you.” And they did according to the word of Moses.
8 And the Lord spoke to Aaron, saying, 9 “Drink no wine or strong drink, you or your sons with you, when you go into the tent of meeting, lest you die. It shall be a statute forever throughout your generations. 10 You are to distinguish between the holy and the common, and between the unclean and the clean, 11 and you are to teach the people of Israel all the statutes that the Lord has spoken to them by Moses.” (English Standard Version)
