“Thou shalt take the fat of the ram, and the rump, and the fat that covereth the lungs, and the caul of the liver, and the two kidneys, and the fat that is upon them, and the right shoulder, because it is the ram of consecration.”

“Hence under the divine law the priest receives the shoulder for sacrifice, and this the right one and separate; to signify that his action should be not only profitable, but even singular; and that he should not merely do what is right among bad men, but transcend even the well-doers among those that are under him in the virtue of his conduct, as he surpasses them in the dignity of his order.”
