Leviticus 9:17-21

¹⁷And he brought near the meat-offering, and he filled his hand thereof, and burnt it upon the altar, beside the burnt-sacrifice of the morning.

¹⁸He slew also the bullock and the ram, the sacrifice of peace-offering which belonged to the people: and the sons of Aaron presented unto him the blood, and he sprinkled it upon the altar round about,

¹⁹Also the fat of the bullock, and of the ram, the rump, and that which covereth the inwards, and the kidneys, and the midriff of the liver;

²⁰And they put these pieces of fat upon the breasts, and he burnt the fat upon the altar;

²¹And with the breasts and the right shoulder Aaron made a waving before the Lord; as Moses had commanded.
