Leviticus 8:33-35

MLV(i) 33 And you* will not go out from the door of the tent of meeting seven days, until the days of your* consecration be fulfilled, for he will consecrate you* seven days. 34 As has been done this day, so Jehovah has commanded to do, to make atonement for you*. 35 And you* will remain at the door of the tent of meeting day and night seven days and keep the charge of Jehovah, that you* not die, for so I am commanded.
