Jamieson, Fausset and Brown on Leviticus 8:33

33. ye shall not go out of the door of the tabernacle of the congregation, &c.--After all these preliminaries, they had still to undergo a week's probation in the court of the tabernacle before they obtained permission to enter into the interior of the sacred building. During the whole of that period the same sacrificial rites were observed as on the first day, and they were expressly admonished that the smallest breach of any of the appointed observances would lead to the certain forfeiture of their lives [Le 8:35].
