Leviticus 8:33–36
You must not go outside the entrance to the Tent of Meeting for seven days, until the days of your ordination are complete; for it will take seven days to ordain you. / What has been done today has been commanded by the LORD in order to make atonement on your behalf. / You must remain at the entrance to the Tent of Meeting day and night for seven days and keep the LORD’s charge so that you will not die, for this is what I have been commanded.”
