Leviticus 8:31-36

And Moses said to Aaron and his sons, “Boil the flesh at the door of the tabernacle of meeting, and eat it there with the bread that is in the basket of consecration offerings, as I commanded, saying, ‘Aaron and his sons shall eat it.’ What remains of the flesh and of the bread you shall burn with fire. And you shall not go outside the door of the tabernacle of meeting for seven days, until the days of your consecration are ended. For seven days he shall consecrate you. As he has done this day, so the LORD has commanded to do, to make atonement for you. Therefore you shall stay at the door of the tabernacle of meeting day and night for seven days, and keep the charge of the LORD, so that you may not die; for so I have been commanded.” So Aaron and his sons did all the things that the LORD had commanded by the hand of Moses.
