Exodus 29:34-36

New Century Version

³⁴ If any of the meat from that sheep or any of the bread is left the next morning, it must be burned. It must not be eaten, because it is holy.

³⁵ “Do all these things that I commanded you to do to Aaron and his sons, and spend seven days appointing them. ³⁶ Each day you are to offer a bull to remove the sins of Aaron and his sons so they will be given for service to the Lord. Make the altar ready for service to the Lord, and pour oil on it to make it holy.
