B. The institution of the Aaronic priesthood chs. 8-10

The account of the consecration of the priests and the priesthood (chs. 8-10) follows the regulations concerning offerings. We have a change in literary genre here from legal to narrative material. The legal material in chapters 1-7 has prepared the reader to understand the narrative in chapters 8-10. The consecration ceremonies involved many of the sacrifices just described. The institution of the Aaronic priesthood constituted the fulfillment of God's commands recorded in Exodus 28-29 and 40. Almost every verse in chapter 8 is a quotation or allusion to commands first given in Exodus 29. Chapter 9 contains freer summaries of the laws in Leviticus 1-7. Thus we learn that Moses adhered strictly to God's instructions.

Until now Israel followed the custom common in the ancient Near East that the father of a family functioned as a priest for his family. The Levites as a tribe now assumed this role for the families of Israel under the leadership of Aaron and his sons.

"God's grace and forgiveness are such that even a sinner like Aaron [who apostatized by building the golden calf] may be appointed to the highest religious office in the nation. Perhaps the closest biblical parallel to Aaron's experience was that of Peter. In spite of his threefold denial of his Lord at Christ's trial, he was reinstated as leader of the apostles after the resurrection."⁷⁵

The three chapters in this section parallel each other in form and content as well as containing contrasts. The effect of this triptych is to present an especially impressive panorama of this great event.⁷⁶

The phrase "Moses did as the Lord commanded him"occurs 16 times in this section (8:4, 5, 9, 13, 17, 21, 29, 34, 36; 9:6, 7, 10, 21; 10:7, 13, 15). It stresses Moses' faithfulness to God (cf. Heb. 3:1-6).

 1. The consecration of the priests and the sanctuary ch. 8

God gave a double command to Moses (vv. 1-3), which Moses obeyed (vv. 4-30). Then Moses gave Aaron a command (vv. 31-35), which Aaron obeyed (v. 36). Within the first section (vv. 1-30) there is a chiastic structure. God commanded Moses to take Aaron and his sons (v. 2) and to assemble the congregation (v. 3). Moses then assembled the congregation (vv. 4-5) and carried out God's orders concerning Aaron and his sons. The second main section (vv. 31-36) acts as a transition by bridging the gap between Aaron's ordination and its completion a week later (cf. 9:1).

 2. The entrance of Aaron and his sons into their office ch. 9

This chapter explains how the priests carried out the duties associated with their induction into their office. The events recorded took place on the eighth day (v. 1), the day after the seven days of consecration. After a week of cleansing, Aaron could now begin to offer sacrifices himself; he no longer had to rely on Moses to offer sacrifices for him.

As noted previously, the structure of chapter 9 is similar to that of chapter 8. Moses commanded Aaron and the "congregation"(vv. 1-4), and the "congregation"obeyed (v. 5). Then Moses commanded Aaron (v. 7), and Aaron obeyed (vv. 8-21). Finally fire from God fell symbolizing His acceptance of the sacrifices (vv. 22-24).

 3. The sanctification of the priesthood ch. 10

One of the remarkable features of chapters 8 and 9 is the obedience of Moses and Aaron to God's commands (cf. 8:4, 9, 13, 17, 21, 29, 36; 9:5, 7, 10, 21). In chapter 10 there is a notable absence of these references. The careful reader notices at once that something is wrong.

"The Lord had only just confirmed and sanctified the sacrificial service of Aaron and his sons by a miracle, when He was obliged to sanctify Himself by a judgment upon Nadab and Abihu, the eldest sons of Aaron (Ex. 6:23), on account of their abusing the office they had received, and to vindicate Himself before the congregation, as one who would not suffer His commandments to be broken with impunity."⁸⁸

"Tragedy and triumph go hand in hand in the Bible and in life. On the very first day of Aaron's high-priestly ministry his two eldest sons died for infringing God's law. In the life of our Lord his baptism by the Spirit was followed by temptation in the wilderness, his triumphal entry into Jerusalem by his crucifixion six days later. In the early Church the healing of the lame man was succeeded by the death of Ananias and Sapphira (Acts 3-5)."⁸⁹
