Leviticus 8:32-34

Amplified Bible

³² And what remains of the meat and of the bread you shall burn in the fire. ³³ You shall not go outside the doorway of the Tent of Meeting for seven days, until the days of your consecration (ordination) are ended; for it will take seven days to consecrate you. ³⁴ As has been done this day, so the Lord has commanded to do for your atonement.
