Lev 10:8 And Yahveh spoke to Aaron, and this is what he said,
Lev 10:9 “Drink no wine or strong drink, you or your sons with you, when you go into the conference tent, or else you will die. It will be a permanent prescription throughout your generations.
Lev 10:10 You are to divide between the holy and the common, and between the contaminated and the pure,
Lev 10:11 and you are to teach the people of Israel all the prescriptions that Yahveh has spoken to them by Moses.”
purity and proclamation
Following the disastrous incident with Nadab and Abihu, it is fair to say that all of the other ordained priests would now be liable to take their jobs quite seriously. So, it makes sense that a job description for the priesthood would come next. The job description consisted of two main tasks: dividing between the holy and the common, and teaching the people of Israel all that Yahveh had prescribed via Moses. Purity of the place and people of God was their responsibility. The priests themselves were to be the first examples of that purity. The LORD commanded Aaron that none of the priests were to ever enter the conference tent under the influence of alcohol. Could this have been the reason Nadab and Abihu attempted to offer the strange fire? Regardless, it is clear that the LORD would tolerate no other influence on the priests except his word. And the LORD also commanded this special group to be the instructors in the moral and ceremonial requirements of God. They were to pass on philosophical and theological purity as well as ecclesiastical and liturgical purity.
LORD, show us how to make our lives thoroughly devoted to you, and pass on that devotion to the next generation.
