Leviticus 8:29-35

²⁹Moses took the breast and waved it as a wave offering to Yahweh. It was Moses' share of the ram for the priests' ordination, as Yahweh had commanded him.

³⁰Moses took some of the anointing oil and the blood that was on the altar; he sprinkled these on Aaron, on his clothes, on his sons, and on his sons' clothes with him. In this way he set apart Aaron and his clothes, and his sons and their clothes to Yahweh.

³¹So Moses said to Aaron and to his sons, “Boil the meat at the entrance to the tent of meeting, and there eat it and the bread that is in the basket of consecration, as I commanded, saying, 'Aaron and his sons will eat it.'

³²Whatever remains of the meat and of the bread you must burn.

³³You must not go out from the entrance of the tent of meeting for seven days, until the days of your ordination are fulfilled. For Yahweh will consecrate you for seven days.

³⁴What has been done this day— Yahweh has commanded to be done to make atonement for you.

³⁵You will stay day and night for seven days at the entrance to the tent of meeting, and keep the command of Yahweh, so you will not die, because this is what I have been commanded.”
