Leviticus 9:19-23

And 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:

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

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

And 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.

And Moses and Aaron went into the tabernacle of the congregation, and came out, and blessed the people: and the glory of the LORD appeared unto all the people.
