Leviticus 8:31-36

³¹Then Moses said to Aaron and to his sons, “Boil the flesh at the doorway of the tent of meeting, and eat it there together with the bread which is in the basket of the ordination offering, just as I commanded, saying, ‘Aaron and his sons shall eat it.’ ³²The remainder of the flesh and of the bread you shall burn in the fire. ³³You shall not go outside the doorway of the tent of meeting for seven days, until the day that the period of your ordination is fulfilled; for he will ordain you through seven days. ³⁴The Lord has commanded to do as has been done this day, to make atonement on your behalf. ³⁵At the doorway of the tent of meeting, moreover, you shall remain day and night for seven days and keep the charge of the Lord, so that you will not die, for so I have been commanded.” ³⁶Thus Aaron and his sons did all the things which the Lord had commanded through Moses.
