The First Ordination

22 Then he presented the other ram, the ram of ordination, and Aaron and his sons laid their hands on the head of the ram. 23 And he killed it, and Moses took some of its blood and put it on the lobe of Aaron's right ear and on the thumb of his right hand and on the big toe of his right foot. 24 Then he presented Aaron's sons, and Moses put some of the blood on the lobes of their right ears and on the thumbs of their right hands and on the big toes of their right feet. And Moses threw the blood against the sides of the altar. 25 Then he took the fat and the fat tail and all the fat that was on the entrails and the long lobe of the liver and the two kidneys with their fat and the right thigh, 26 and out of the basket of unleavened bread that was before the Lord he took one unleavened loaf and one loaf of bread with oil and one wafer and placed them on the pieces of fat and on the right thigh. 

If you have ever been to the ordination service for a deacon, elder, priest, missionary, evangelist, or other church leader, it probably was a little different than this first recorded one: that of Aaron and his sons. But the imagery is very powerful here. To serve as priest one had to be truly set apart for service. The blood on the ear, thumb, and toe demonstrated a commitment to hear and speak God's word, to serve Him with one's hands, and to live(walk) in total obedience to Him. God asks no less of us as His priests today - not just the leaders mentioned above, but His whole Kingdom of Priests - each and every confessing follower.

Why Not That?

Leviticus 7:22 The Lord spoke to Moses, saying, 23 “Speak to the people of Israel, saying, You shall eat no fat, of ox or sheep or goat. 24 The fat of an animal that dies of itself and the fat of one that is torn by beasts may be put to any other use, but on no account shall you eat it. 25 For every person who eats of the fat of an animal of which a food offering may be made to the Lord shall be cut off from his people. 26 Moreover, you shall eat no blood whatever, whether of fowl or of animal, in any of your dwelling places. 27 Whoever eats any blood, that person shall be cut off from his people.”

The reference here is back to the peace offering, detailed in chapter 3, which was for reconciliation and fellowship between God and a sincere worshipper.  Nothing was to be held back for oneself but totally offered to God. In no cases was the blood to be eaten/drunk, as "the life is in the blood", and many pagan rituals involved the drinking of blood. We see here that even animals that died not from sacrifice but were potentially sacrifices were to be treated the same way.  No sacrifice was to be taken lightly or made for any selfish reasons.  All was Holy to the Lord.

Sin Offering Eater

Leviticus 6:24 The Lord spoke to Moses, saying, 25 “Speak to Aaron and his sons, saying, This is the law of the sin offering. In the place where the burnt offering is killed shall the sin offering be killed before the Lord; it is most holy. 26 The priest who offers it for sin shall eat it. In a holy place it shall be eaten, in the court of the tent of meeting. 

God spent over two chapters giving instructions for the sin offering, when it was to be offered, and by whom.  He now told about what to do with it.  It was to be eaten by the priests who had been made holy for this service.  God was very specific about who, when, and where it was to be eaten. Fast forward to the upper room, where Jesus said: "This is My body, given for you; take and eat." They were being told to eat the sin offering.  In that same setting He told them that they were made holy through their faith in Him. They, and those after them, were His priests, made holy through faith, who gather in remembrance of Him and what He has done.  This pictures God's acceptance of what Christ has done for us, just as the eating of the sin offering by the priest pictured God accepting the sin offering.
