Leviticus 8:28-35

²⁸And Moses took them from their hands, and they were burned on the altar on the burned offering, as a priest's offering for a sweet smell, an offering made by fire to the Lord.

²⁹And Moses took the breast, waving it for a wave offering before the Lord; it was Moses' part of the sheep of the priest's offering, as the Lord gave orders to Moses.

³⁰And Moses took some of the holy oil and of the blood which was on the altar and put it on Aaron and on his robes, and on his sons and on his sons' robes; and made Aaron holy, and his robes and his sons and his sons' robes with him.

³¹And Moses said to Aaron and to his sons, The flesh is to be cooked in water at the door of the Tent of meeting, and there you are to take it as food, together with the bread in the basket, as I have given orders, saying, It is the food of Aaron and his sons.

³²And that which is over of the flesh and of the bread is to be burned with fire.

³³And you are not to go out from the door of the Tent of meeting for seven days, till the days for making you priest are ended; for this will be the work of seven days.

³⁴What has been done this day, has been ordered by the Lord to take away your sin.

³⁵And you are to keep watch for the Lord at the door of the Tent of meeting day and night for seven days, so that death may not come to you: for so he has given me orders.
