Leviticus 8:29-31

²⁹and Moses taketh the breast, and waveth it — a wave-offering before Jehovah; of the ram of the consecrations it hath been to Moses for a portion, as Jehovah hath commanded Moses.

³⁰And Moses taketh of the anointing oil, and of the blood which is on the altar, and sprinkleth on Aaron, on his garments, and on his sons, and on the garments of his sons with him, and he sanctifieth Aaron, his garments, and his sons, and the garments of his sons with him.

³¹And Moses saith unto Aaron, and unto his sons, 'Boil ye the flesh at the opening of the tent of meeting, and there ye do eat it and the bread which is in the basket of the consecrations, as I have commanded, saying, Aaron and his sons do eat it.
