Leviticus 8:32-34

Revised Standard Version Catholic Edition

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