Exodus 29:33-35

New International Reader's Version

³³ These are the offerings to pay for their sins. They must eat them. The offerings must be made when Aaron and his sons are set apart and prepared to serve the Lord. No one else can eat them. They are sacred. ³⁴ When you prepare Aaron and his sons to serve me, you will sacrifice the ram and the bread. If any parts of the ram or bread are left until morning, burn them up. They must not be eaten. They are sacred.

³⁵ “Do everything I have commanded you to do for Aaron and his sons. Take seven days when you prepare them to serve the Lord.
