Leviticus 8:28-35

²⁸And Moses took the breast, and separated it for a heave-offering before the Lord, from the ram of consecration; and it became Moses' portion, as the Lord commanded Moses.

²⁹And Moses took of the anointing oil, and of the blood that was on the altar, and sprinkled it on Aaron, and on his garments, and his sons, and the garments of his sons with him.

³⁰And he sanctified Aaron and his garments, and his sons, and the garments of his sons with him.

³¹And Moses said to Aaron and to his sons, Boil the flesh in the tent of the tabernacle of witness in the holy place; and there ye shall eat it and the loaves in the basket of consecration, as it has been appointed me, the Lord saying, Aaron and his sons shall eat them.

³²And that which is left of the flesh and of the loaves burn ye with fire.

³³And ye shall not go out from the door of the tabernacle of witness for seven days, until the day be fulfilled, the day of your consecration; for in seven days shall he consecrate you,

³⁴as he did in this day on which the Lord commanded me to do so, to make an atonement for you.

³⁵And ye shall remain seven days at the door of the tabernacle of witness, day and night; ye shall observe the ordinances of the Lord, that ye die not; for so has the Lord God commanded me.
