Leviticus 8:33-36

The time of appointing will last seven days; you must not go outside the entrance of the Meeting Tent until that time is up. Stay there until the time of your appointing is finished. The LORD commanded the things that were done today to remove your sins so you will belong to him. You must stay at the entrance of the Meeting Tent day and night for seven days. If you don’t obey the LORD’s commands, you will die. The LORD has given me these commands.” So Aaron and his sons did everything the LORD had commanded through Moses.
