Leviticus 9:18-22

¹⁸He immolated also the bullock and the ram, the peace offerings of the people: and his sons brought him the blood, which he poured upon the altar round about.

¹⁹The fat also of the bullock, and the rump of the ram, and the two little kidneys, with their fat, and the caul of the liver,

²⁰They put upon the breasts. And after the fat was burnt upon the altar,

²¹Aaron separated their breasts, and the right shoulders, elevating them before the Lord, as Moses had commanded.

²²And stretching forth his hands to the people, he blessed them. And so the victims for sin, and the holocausts, and the peace offerings being finished, he came down.
