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 of the door of the tabernacle of the congregation in seven days, until the days of your consecration be at an end: for seven days shall he consecrate you.

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

³⁵Therefore shall ye abide at the door of the tabernacle of the congregation day and night seven days, and keep the charge of the LORD, that ye die not: for so I am commanded.
