Leviticus 8:28-30

New Century Version

²⁸ Then Moses took them from their hands and burned them on the altar on top of the burnt offering. So this was the offering for appointing Aaron and his sons as priests. It was an offering made by fire to the Lord, and its smell was pleasing to him. ²⁹ Moses also took the breast and presented it as an offering before the Lord. It was Moses’ share of the male sheep used in appointing the priests, as the Lord had commanded him.

³⁰ Moses took some of the special oil and some of the blood which was on the altar, and he sprinkled them on Aaron and Aaron’s clothes and on Aaron’s sons and their clothes. In this way Moses made Aaron, his clothes, his sons, and their clothes holy for the Lord.
