“I will meet there with the sons of Israel, and it shall be consecrated by My glory. I will consecrate the tent of meeting and the altar; I will also consecrate Aaron and his sons to minister as priests to Me. I will dwell among the sons of Israel and will be their God. They shall know that I am the Lord their God who brought them out of the land of Egypt, that I might dwell among them; I am the Lord their God” (Exodus 29:43-46, NASB).
This chapter gives regulations for the consecration of the priests that would minister to God in the Tabernacle. The priests were to be ordained for service in the Tabernacle through purification rites and the offering of burnt sacrifices for atonement of sin. First, the priests were to be washed with water in the doorway of the Tabernacle. Then their priestly garments were placed on them and anointing oil poured over their heads.
