Leviticus 8:30-32

Amplified Bible

³⁰ So Moses took some of the anointing oil and some of the blood which was on the altar and sprinkled it on Aaron and his garments, and also on his sons and their garments with him; so Moses consecrated Aaron and his garments, and his sons and his sons’ garments with him.

³¹ Then Moses said to Aaron and to his sons, “Boil the meat at the doorway of the Tent of Meeting and eat it there together with the bread that is in the basket of the consecration (ordination) offering, just as I commanded, saying, ‘Aaron and his sons shall eat it.’ ³² And what remains of the meat and of the bread you shall burn in the fire.
