Each leader of the tribes of Israel had a different job and function based on how the tribes were placed around the tabernacle. They had to go through a ceremonial pattern in order to be “ordained” to the job God was calling them to do. Every prince accepted their anointing. All the names listed here are a play on words that teach us about God’s love and the Messiah’s sacrifice.
God, through Moshe (Moses), consecrates His mediator, Aharon (Aaron). There is a clear transfer of spiritual authority from Moshe to Aharon at this point. This is a foreshadowing of God’s consecration of Yeshua, our Messiah as our High Priest, who had to walk a sacrificial walk for us that we could hear, do and walk in God’s word as He does. After Moshe consecrated Aharon and his sons, there was no longer any doubt as to how God has chosen to be the mediator between Himself and His people.
The book of Leviticus is not about laws but about how to be a priest. A lot of these lessons are physical but there’s more of the Spirit in these chapters than a cursory view might suggest.
Moses was shown many wonderful things on the Mountain, including the ritual to anoint his older brother Aaron and Aaron’s four sons as priests before Him. The overall theme of these two chapters is atonement: atonement for the people and for Aaron and his sons. Even inanimate objects, such as Aaron’s wardrobe, the altar and the Tabernacle itself have to be atoned before they can perform a sacred use.
