Leviticus 8:29-31 New International Version - UK (NIVUK)
29 Moses also took the breast, which was his share of the ordination ram, and waved it before the Lord as a wave offering, as the Lord commanded Moses.
30 Then Moses took some of the anointing oil and some of the blood from the altar and sprinkled them on Aaron and his garments and on his sons and their garments. So he consecrated Aaron and his garments and his sons and their garments.
31 Moses then said to Aaron and his sons, ‘Cook the meat at the entrance to the tent of meeting and eat it there with the bread from the basket of ordination offerings, as I was commanded: “Aaron and his sons are to eat it.”
