Leviticus 8:32-35

³²And that which remaineth of the flesh and of the bread shall ye burn with fire.

³³And ye shall not go out from the door of the tent of meeting seven days, until the days of your consecration be fulfilled; for He shall consecrate you seven days.

³⁴As hath been done this day, so the LORD hath commanded to do, to make atonement for you.

³⁵And at the door of the tent of meeting shall ye abide day and night seven days, and keep the charge of the LORD, that ye die not; for so I am commanded.
