(Cross reference with Leviticus Chapter 8)
Note: Under God’s direction, Moses has set aside his brother Aaron and all of his sons: Nadab, Abihu, Eleazar and Ithamar (Chapter 28) for the office of the Priesthood. They were given their official priestly attire. Aaron served as the 1st high priest and in succession, it was by God’s design that all of the future high priest were to come from Aaron’s genealogy. "Although the holiness of their office was reflected in their outward dress, it was equally necessary, because of their sinfulness nature, that they should be sanctified (spiritually) through a special consecration ritual for the administration of their office. The directions now given for the consecration were carried out in Leveticus 8.
I. Consecration of the Priests (Aaron and his sons) Exodus 29:1-9
A. Offerings for the consecration process (vs. 1-3)
1 young bull and 2 rams unblemished, unleavened bread and unleavened wheat cakes tempered with oil and wafers anointed with oil
Consecrating the priests was a solemn ceremony for 2 reasons:
1. The people were to see that the office of the priesthood was an exalted office, an important office of great magnitude completely sanctioned by God.
2 The Priest were to see that they could not take their appointment to the priesthood lightly and they were to understand that the service they performed for God wasn’t just for the people’s benefit but for them too. They had to consecrate themselves COMPLETELY AND EVERYTIME they served in their priestly capacity.
B. Bring them to the door of the tabernacle of the Congregation and wash them
4 things concerning the consecration of the Priest:
The priest had to be clean spiritually
They had to be clothed in the righteousness of God
They had to be empowered by the Spirit of God (Holy Spirit)
Water usage signified 3 things:
1. In their relationship with God, it signified a transition from an unprivileged to a privileged state.,
2. It signified a change in their status and social state from being “common” to being “consecrated”
3. Signified the necessity and importance a person serving in ministry serving with moral purity and holiness. When Aaron and his sons were constituted priests, they were washed, that element importing that they were not only elevated from the condition of common Israelites to a holy office, but that they required to cultivate personal purity (Isa 52:11; John 13:10; 2 Cor. 7:1; 1 Peter 3:21)
II. The Sacrificial Offerings in Behalf of the Priest Exodus 29:10-30
A. First: Bring the young bull (the Sin offering) vs. 10-14
Step by Step Procedure:

kidneys- (fat and all) and burn them on the altar.
6. Burn the meat and all other parts of the bull outside the city.
Note: There must be a sin-offering, to make atonement for the priest.
a. The Priest must first make a “sin” offering for their own sin, before they could make atonement for the people, (Heb 7:27, 28).
b. They were to put their hand on the head of their sacrifice (v. 10), confessing that they deserved to die for their own sin, and desiring that the killing of the beast might expiate their guilt, and be accepted by as a vicarious satisfaction.
c. This “sin” offering was used as other sin-offerings were; only, whereas the flesh of other sin-offerings was eaten by the priests (Lev 10:18), in token of the priest's taking away the sin of the people, this was appointed to be all burnt without the camp (v. 14).
d. The Sin offering signified the imperfection of the legal dispensation; for the sins of the priests themselves could not be taken away by those sacrifices, but they must expect a better high priest(Jesus Christ) and a better “ blood” sacrifice.

Note: There must be a burnt-offering, a ram wholly burnt, to the honor of God. This offering signified that the priest had completely dedicated themselves to God and to his service, They were presenting their bodies as a living sacrifice, wholly and acceptable to God because as “called” servants, this was their “reasonable service.
Important: The sin-offering must first be offered before the burnt-offering; until God removes their sin guilt, no acceptable service can be performed, Isaiah 6:7

Note: Concerning the Ram of Consecration. Once the priest had been cleansed and dedicated the next thing they did was symbolically had communion with God, as they ate their portion of the sacrificed ram.
a. The Ears, hands, and feet (v. 20) were dedicated to God as the priiest were to listen to God’s instructions and obey his word.
b. The "cleansing blood" and "sanctifying oil" were sprinkled not only upon the men, but upon their official garments (v. 21), symbolizing that God had both consecrated and empowered them for their assigned service.

(The breast and the thigh of the ram of the installation offering were given to Moses as to the officiating priest (vv. 26-28). Ordinarily, as here ordained, this portion would go to the priest)
III. Passing of the Priestly Garments Exodus 29:29-30

Jesus supped with them, and they with him. The eating of the flesh sacrificed for the atonement signified they receiving the atonement. As it was the expressed is (Romans 5:11), their thankful acceptance of the benefit of it, and their joyful communion with God thereupon, which was the true intent and meaning of a feast upon a sacrifice.
