Leviticus 8:33-35

New Revised Standard Version Catholic Edition

³³ You shall not go outside the entrance of the tent of meeting for seven days, until the day when your period of ordination is 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 You shall remain at the entrance of the tent of meeting day and night for seven days, keeping the Lord’s charge so that you do not die; for so I am commanded.”
