Leviticus 8:28–33

²⁸Then Moses took them from their hands and burned them on the altar with the burnt offering. This was an ordination offering with a pleasing aroma, a food offering to the Lord. ²⁹And Moses took the breast and waved it for a wave offering before the Lord. It was Moses’ portion of the ram of ordination, as the Lord commanded Moses.

³⁰Then ^oMoses took some of the anointing oil and of the blood that was on the altar and sprinkled it on Aaron and his garments, and also on his sons and his sons’ garments. So he consecrated Aaron and his garments, and his sons and his sons’ garments with him.

³¹And Moses said to Aaron and his sons, “Boil the flesh at the entrance of the tent of meeting, and there eat it and the bread that is in the basket of ordination offerings, as I commanded, saying, ‘Aaron and his sons shall eat it.’ ³²And what remains of the flesh and the bread you shall burn up with fire. ³³And you shall not go outside the entrance of the tent of meeting for seven days, until the days of your ordination are completed, for it ^pwill take seven days to ordain you.
