Leviticus 8:36

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

And 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.

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

Therefore 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.
