And the LORD spake unto Moses after the death of the two sons of Aaron, when they offered before the LORD, and died;
After the death of the two sons of Aaron. It is thought by some that this chapter has been transposed in the sacred record out of its right place, which was immediately after the narrative of the deaths of Nadab and Abihu (Leviticus 10:1-5). That appalling catastrophe must have filled Aaron with painful apprehensions lest the guilt of those two sons might be entailed on his house, or that other members of his family might share the same fate by some irregularities or defects in the discharge of their sacred functions. And therefore this law was established, by the due observance of whose requirements the Aaronic order would be securely was established, by the due observance of whose requirements the Aaronic order would be securely maintained and accepted in the priesthood.
