Leviticus 8:31-35

8:31 Then Moses said to Aaron and his sons, “Boil the meat at the entrance of the Meeting Tent, and there you are to eat it and the bread which is in the ordination offering basket, just as I have commanded, saying, ‘Aaron and his sons are to eat it,’ 8:32 but the remainder of the meat and the bread you must burn with fire. 8:33 And you must not go out from the entrance of the Meeting Tent for seven days, until the day when your days of ordination are completed, because you must be ordained over a seven-day period. 8:34 What has been done on this day the Lord has commanded to be done to make atonement for you. 8:35 You must reside at the entrance of the Meeting Tent day and night for seven days and keep the charge of the Lord so that you will not die, for this is what I have been commanded.”
