Leviticus 16:1

“And the Lord spake unto Moses, after the death of the two sons of Aaron, etc.] That is, either immediately after their death, and so this chapter would have stood in its natural order next to the tenth; or else after the above laws concerning uncleanness on various accounts were delivered out, designed to prevent the people entering into the tabernacle defiled, whereby they would have incurred the penalty of death; wherefore, as Aben Ezra observes, after the Lord had given cautions to the Israelites, that they might not die, he bid Moses to caution Aaron also, that he might not die as his sons died; these were Nadab and Abihu: when they offered before the Lord, and died; offered strange…”

“HOW THE HIGH PRIEST MUST ENTER INTO THE HOLY PLACE. (Lev. 16:1-34) after the death of the two sons of Aaron, when they offered before the Lord, and died--It is thought by some that this chapter has been transposed out of its right place in the sacred record, which was immediately after the narrative of the deaths of Nadab and Abihu [Lev. 10:1-20]. That appalling catastrophe must have filled Aaron with painful apprehensions lest the guilt of these 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…”

“The reference to the death of Nadab and Abihu is a notice of the occasion on which the instructions were given, well calculated to add point and emphasis to the solemn admonition to the high priest in the second verse. The death of his sons Leviticus 10:2, for drawing near to Yahweh in an unauthorized manner, was to serve as a warning to Aaron himself never to transgress in this respect. return to 'Top of Page'”

“16:1-34 The Day of Atonement, the tenth day of the seventh month (see 16:29; 23:27; Num 29:7), was the most solemn day of the year for Israelites. It was the only required fast, and it was a Sabbath of rest for all the people (Lev 23:32). Introduced by the Festival of Trumpets (Num 29:1, 7-11), it was the day when the corporate sins of the community were atoned for. Only the high priest (Aaron) could officiate, because only he could represent all the people, including other priests (Aaron’s sons). The Day of Atonement is celebrated today as Yom Kippur.”

“Lev 10:1, Lev 10:2 Leviticus 16:2”

“The chronological link connecting the following law with the death of the sons of Aaron ( Lev 10:1-5) was intended, not only to point out the historical event which led to the appointment of the day of atonement, but also to show the importance and holiness attached to an entrance into the inmost sanctuary of God. The death of Aaron's sons, as a punishment for wilfully "drawing near before Jehovah," was to be a solemn warning to Aaron himself, "not to come at all times into the holy place within the vail, before the mercy-seat upon the ark," i.e., into the most holy place (see Exo 25:10.), but only at the time to be appointed by Jehovah, and for the purposes instituted by Him, i.e.,…”
