Leviticus 9:18-22

¹⁸He also killed the bull and the ram, the sacrifice of peace offerings, which was for the people. Aaron’s sons delivered to him the blood, which he sprinkled around on the altar;

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 burnt 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 towards the people, and blessed them; and he came down from offering the sin offering, and the burnt offering, and the peace offerings.
