Leviticus 8:29

25 And Moses took the fat—the fat tail, all the fat that was on the entrails, the lobe of the liver, and both kidneys with their fat—as well as the right thigh.

26 And from the basket of unleavened bread that was before the LORD, he took one cake of unleavened bread, one cake of bread made with oil, and one wafer, and he placed them on the fat portions and on the right thigh.

27 He put all these in the hands of Aaron and his sons and waved them before the LORD as a wave offering.

28 Then Moses took these from their hands and burned them on the altar with the burnt offering. This was an ordination offering, a pleasing aroma, an offering made by fire to the LORD.

29 He also took the breast—Moses’ portion of the ram of ordination—and waved it before the LORD as a wave offering, as the LORD had commanded him.

30 Next, Moses took some of the anointing oil and some of the blood that was on the altar and sprinkled them on Aaron and his garments, and on his sons and their garments. So he consecrated Aaron and his garments, as well as Aaron’s sons and their garments.

31 And Moses said to Aaron and his sons, “Boil the meat at the entrance to the Tent of Meeting and eat it there with the bread that is in the basket of ordination offerings, as I commanded, saying, ‘Aaron and his sons are to eat it.’

32 Then you must burn up the remainder of the meat and bread.

33 You must not go outside the entrance to the Tent of Meeting for seven days, until the days of your ordination are complete; for it will take seven days to ordain you.
