Leviticus 9:20-22

Amplified Bible

²⁰ they now put the portions of fat on the breasts; and Aaron offered the fat up in smoke on the altar. ²¹ But the breasts and the right thigh Aaron presented as a wave offering before the Lord, just as Moses had commanded.

²² Then Aaron lifted his hands toward the people and blessed them, and came down [from the altar of burnt offering] after presenting the sin offering, the burnt offering, and the peace offerings.
