Leviticus 8:33-35

Revised Standard Version

³³ And you shall not go out from the door of the tent of meeting for seven days, until the days of your ordination are completed, for it will take seven days to ordain you. ³⁴ As has been done today, the Lord has commanded to be done to make atonement for you. ³⁵ At the door of the tent of meeting you shall remain day and night for seven days, performing what the Lord has charged, lest you die; for so I am commanded.”
