Leviticus 9:20 KJV

18He slew also the bullock and the ram for a sacrifice of peace offerings, which was for the people: and Aaron’s sons presented unto him the blood, which he sprinkled upon the altar round about,

19And the fat of the bullock and of the ram, the rump, and that which covereth the inwards, and the kidneys, and the caul above the liver:

20And they put the fat upon the breasts, and he burnt the fat upon the altar:

21And the breasts and the right shoulder Aaron waved for a wave offering before the LORD; as Moses commanded.

22And Aaron lifted up his hand toward the people, and blessed them, and came down from offering of the sin offering, and the burnt offering, and peace offerings.
