Verses 1–5
LEVITICUS- CHAPTER SIXTEEN
Verses 1-5:
Verse I refers to Le 10:1, 2, the death of Nadab and Abihu, when they offered "strange fire" upon the altar. The sin and death of these two sons did not disqualify Aaron from ministering in the office of high priest.
God placed severe restrictions upon the high priest’s appearance in the Holy of Holies. This was limited to an annual occasion, described in this text and designated as "The Day of Atonement," Yom Kippur, the "Day of Covering," see Heb 9:7-25; 10:19-22.
To officiate in his capacity in the Yom Kippur ceremonies, Aaron must first be clothed in proper garments. These differed from the ceremonial garments of the high priest described in Ex 28:1-39. On the occasion of the text, he was to wear white linen garments: coat, breeches, girdle (belt), and mitre (turban). This symbolized the holiness and purity necessary to appear before God, Ps 24:3, 4; Heb 12:14. This symbolism is strengthened by the requirement that the high priest must bathe before he donned these garments.
Aaron was to bring certain sacrifices to the brazen altar. One was a bullock for a Sin Offering, Le 4:3-12, and a ram for a Burnt Offering, Le 1:3-9. This was to be offered for his own sin, see Heb 5:1-4.
The second offering consisted of two kids (young goats) for a Sin Offering, Le 4:27-31. This was to be offered for the sins of "the common people (through) ignorance" (Le 4:27).
