Leviticus 9:20-23

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 lift up his hand towards the people, and blessed them, and came down from offering of the sin offering, and the burnt offering, and peace offerings.

²³And 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.
