Leviticus 8:28–33

²⁸Then Moses took them from their hands and burned them on the altar with the burnt offering. This was an ordination offering for a pleasing aroma, a fire offering to the Lord. ²⁹He also took the breast and waved it before the Lord as a presentation offering; it was Moses’ portion of the ordination ram as the Lord had commanded him.

³⁰Then Moses took some of the anointing oil and some of the blood that was on the altar and sprinkled them on Aaron and his garments, as well as on his sons and their garments. In this way he consecrated Aaron and his garments, as well as his sons and their garments. ⁿ

³¹Moses said to Aaron and his sons, “Boil the meat at the entrance to the tent of meeting and eat it there with the bread that is in the basket for the ordination offering as I commanded: ^oAaron and his sons are to eat it. ^p32You must burn up what remains of the meat and bread. ^q33You must not go outside the entrance to the tent of meeting for seven days, until the time your days of ordination are completed, because it will take seven days to ordain you. ^r
