Leviticus 8:32-34

New Revised Standard Version, Anglicised

³² and what remains of the flesh and the bread you shall burn with fire. 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.
