Leviticus 8:32-35

³²And that which remaineth of the flesh and of the bread, you shall burn in the fire.

³³And form the door of the tabernacle of ordinance ye shall not go forth (for) seven days, until the day that the days of your oblation be completed; for seven days shall your oblations be offered,

³⁴as hath been done this day, (as) the Lord commanded to be done to make atonement for you.

³⁵And at the door of the tabernacle of ordinance ye shall dwell seven days and nights, and watch the watches of the Word of the Lord, that you die not; for so am I commanded.
