Leviticus 9:21

19and the fat of the bull and of the ram, the fat tail, and that which covers the innards, and the kidneys, and the cover of the liver;

20and they put the fat upon the breasts, and he burned the fat on the altar.

21Aaron waved the breasts and the right thigh for a wave offering before the LORD, as Moses commanded.

22Aaron lifted up his hands toward the people, and blessed them; and he came down from offering the sin offering, and the burnt offering, and the peace offerings.

23Moses and Aaron went into the Tent of Meeting, and came out, and blessed the people; and the LORD’s glory appeared to all the people.
