Leviticus 8:33-36

33And 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.

34As he has done this day, so the Lord has commanded to do, to make atonement for you.

35Therefore 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.”

36So Aaron and his sons did all the things that the Lord had commanded by the hand of Moses.
