Leviticus 8:26-31

26and out of the basket of unleavened bread that was before the Lord he took one unleavened loaf and one loaf of bread with oil and one wafer and placed them on the pieces of fat and on the right thigh.

27And he put all these in the hands of Aaron and in the hands of his sons and waved them as a wave offering before the Lord.

28Then Moses took them from their hands and burned them on the altar with the burnt offering. This was an ordination offering with a pleasing aroma, a food offering to the Lord.

29And Moses took the breast and waved it for a wave offering before the Lord. It was Moses' portion of the ram of ordination, as the Lord commanded Moses.

30Then Moses took some of the anointing oil and of the blood that was on the altar and sprinkled it on Aaron and his garments, and also on his sons and his sons' garments. So he consecrated Aaron and his garments, and his sons and his sons' garments with him.

31And Moses said to Aaron and his sons, "Boil the flesh at the entrance of the tent of meeting, and there eat it and the bread that is in the basket of ordination offerings, as I commanded, saying, 'Aaron and his sons shall eat it.'
