Leviticus 8:32-35

³²And that which is over of the flesh and of the bread is to be burned with fire.

³³And you are not to go out from the door of the Tent of meeting for seven days, till the days for making you priest are ended; for this will be the work of seven days.

³⁴What has been done this day, has been ordered by the Lord to take away your sin.

³⁵And you are to keep watch for the Lord at the door of the Tent of meeting day and night for seven days, so that death may not come to you: for so he has given me orders.
