Three offerings are brought for the ordination of Aaron’s sons:
1. a sin offering (verse 14),
2. a burnt offering (fresh 18) and
3. an offering of ordination (verse 22).
The offering of ordination is a special form of the peace offering.
Aaron and his sons lay their hands on all three offerings. As we have seen before, laying on the hands means identification with that on which the hands are laid. If you want to be a priest, you must identify yourself with the work of the Lord Jesus.
In the sin offering it means that, in order to perform priestly service, I must be well aware that all my sins have passed to the Lord Jesus, that He has borne my sins and has been judged for them. Equally, I may and must be aware that I stand before God in all the pleasantness of the offering of the Lord Jesus that He brought to God as burnt offering. I derive my dignity to be a priest not from something in myself, but exclusively from Him.
If I am now ordained to God as a priest, I can only accomplish my task as a priest devoted to God if I see that the Lord Jesus is the great Priest, who is perfectly devoted to God in everything. He has always done perfectly everything the Father has commanded Him to do (Jn 6:3838For I have come down from heaven, not to do My own will, but the will of Him who sent Me.; 10:1818No one has taken it away from Me, but I lay it down on My own initiative. I have authority to lay it down, and I have authority to take it up again. This commandment I received from My Father.”; 14:3131but so that the world may know that I love the Father, I do exactly as the Father commanded Me. Get up, let us go from here.).
It is remarkable that all the offerings here are brought by Moses. The priests are not yet able to do so, they are not yet ordained. Moses can do that. He doesn’t need ordination. He is a picture of the Lord Jesus as the Teacher of righteousness.
We have already seen what happens to the sin offering and the burnt offering in Leviticus 4 and Leviticus 1, respectively. This also applies to the offering of ordination, although this has not been explicitly mentioned. The offering of ordination is a special kind of peace offering. In Leviticus 7 it is mentioned separately in the summary of the laws on sacrifices, but in connection with the peace offering (Lev 7:3737This is the law of the burnt offering, the grain offering and the sin offering and the guilt offering and the ordination offering and the sacrifice of peace offerings,).
The animal of the ordination offering is a ram, as is the burnt offering. This means that our ordination and devotion as priests must have the same character as the burnt offering. Our ordination and dedication must be of the same features as the ordination and dedication of the Lord Jesus (cf. Eph 5:1-21Therefore be imitators of God, as beloved children;2and walk in love, just as Christ also loved you and gave Himself up for us, an offering and a sacrifice to God as a fragrant aroma.). That means the commitment of our whole person.
That the ordination offering is a special kind of peace offering is evident from the special application of a part of the blood. The blood of the ordination offering is applied to three body parts (verses 23-24). The blood of Christ, His dedication to death, is the foundation of our dedication.
The blood is first applied to the ear. The ear speaks of listening, hearing, obeying. This is where every true priestly service begins. First we must listen to know what the Lord asks of us, how He wants everything to be. Only then can we hold act (hand) and walk (foot), in accordance with the meaning and value of the blood.
